Bill, I think you are creating a wrong impression with the words "hopefully in a setting where we can have an open invitation to ALL who'd like to attend, rather than being limited to a specific number of potential openings...". NOBODY was told that there is not enough space for them. In fact, Robert Lofthouse already offered his unlimited venue up north on 11 July, but the final headcount made John's place the right fit. (A big batch of posts with invites and pictures have been deleted from this thread). Please don't make it sound like the door was locked - as we can attest, John's doors can't even close properly, never mind be locked!
Robert, can you think of an exhibition/expo covering SB-type stuff in the UK? Maybe pick a date around that?
