I will reply to comments one at a time
Chamaco
At the request of some teachers I did allow some Advanced in as "watching' members - there are still a few, a very few who were/are able to accept the restraints put upon them. The rest caused trouble with a capital T .
Just a couple of days ago I had a member classing himself as an Intermediate tell me I should not let a BEGINNER play in my BEGINNER Intermediate Tournament - - "until they learned more than the basics" !!!
You are right some do apply as Nov/Beg/Int and are given a membership without question - few remain for long , they forget to change their profile when they come in from the MBC or when they enter a BIL tournament, then too the real BILlies are vigilant in the MBC and I am often greeted with - '....' is an Adv

!! As you said "your friend does not like cheating' - well neither do I like those that do - for them I will do nothing.
You have it totally WRONG the scope of the BIL is NOT
to improve the general skill of the BBO community.
The BIL is my Private Club and the scope of the BIL - IS , has ALWAYS been and WILL ALWAYS be to HELP the BEGINNER to learn to play bridge.
I included Intermediates for 3 reasons
1. Beginners cannot improve, lift their game just playing amongst themselves , we need to be challenged and that means playing with those more skilled than ourselves.
2. Most of the Seniors at my f2f club have never heard of the conventions my class use because of the information I have gathered on BBO. So the BIL can give those players, as they come online, a place to upskill and thus hold their own in the MBC. Whilst doing that my members can benefit by playing with them - they may not know the modern conventions but their declarer/defense play can be pretty canny !
3. And too it leaves room for those that join as Beginners to continue to learn and advance their playing capabilities to the point where they are comfortable playing with/against the MBC Advanced community
For the Intermediates as part of our first birthday 'celebrations' I am instituting an Honorary Graduate membership so that when they feel they have upskilled sufficiently they do not have to leave the BIL because they now class themselves as Advanced but will be able to remain and continue being helpful.
I had the selfish notion that I could learn to play bridge too - not to be !! The running of the BIL takes up all of my spare time. My Hands record shows that in the 315 days the BIL has been in existence I have played on just 25 occasions with an average stay of 11 boards. Hardly likely to improve at that rate !! and yet I spend never less than 8 hours a day, 7 days a week on BIL business - and you say that letting Advanced join is "not an extra committment in term of time of resources. !!!
My advice Chamaco - start your own PRIVATE CLUB for Int/Adv .I am sure Oliver and others will be pleased to come and teach for you.
BTW - your reply to Sceptic - (believe me I have asked ) Chat cannot be disabled as you suggest.

PAULHAR - the reply you got from me was " I thought I only invited beginners" (from the MBC - via Lobby notice) (all BIL members General and Honorary <Advanced to World Class> were of course personally invited ) how many of them came I have no way of knowing. The Lecture Hall has no restrictions on entry.
You say - "I fully respect Maureen's decision to shut me out of the lesson" when , which lesson ?? According to my memory I sent you an information sheet outlining the various Honorary member categories the BIL offers and invited you to ask for temporary entry to the BIL so that you could assess what is going on in there and then to decide whether you want to offer to help the membership . You have not, to date, expressed a wish to do that.
Thank you for summing up your experience in the MBC trying to teach beginners. No more needs to be said . That is it ! The lessons that are offered daily in the BIL are suited for beginners who have moved beyond the basics and the intermediates.
It was for that reason that JAKE (and the BIL's beginner members are truly indebted to him ) focused on a Lecture Hall presentation because with that format the lesson cannot be taken over by anyone. If it seems too simple for some they can simply flick their 'back' button and be gone. We shall be having more of these.

42 - your comment #3 'will leave' - sadly no, far too many of them do NOT !! They send private messages to the teacher 'arguing a point' distracting the teacher. They make smart/nasty comments to the other kibitzers and when they get an ear full from me they then start sending 'put down' messages by private chat to the hapless beginner . I have had members asking to be replaced at a table as they need to shut off their computer because THEY ARE IN TEARS !!!!!! ( not an isolated case ! ) yet those lessons had been CLEARLY advertised as being aimed at BEGINNERS
I have asked to have chat facilities to control this - they are not available to private clubs - so my work around is simple NO Advanced
Advanced to the World's Best are WELCOME in the BIL but only when they come willing to help my members in an Honorary Member capacity . To be given that they must contact me direct with their offer to help.
The BIL already has a WONDERFUL group of people HELPING DAILY - and I cannot ever fully express my gratitude to them for all they do and the difference they have made
