So, I can't get my yahoo openID to work on the site. I wrote an email to the contact given on the site about a month ago asking to go on the wait list but there's been no response either way. I'm not really expecting a place at this stage but it would be nice to have a response to say that so I can actually free up the time slot (or not).
For some reason Yahoo! OpenID doesn't play well with others (I've encountered the same problem). Can you try with a myopenid.com? I know that works. We are not manually adding people to the waiting list, sorry.
As to numbers, the organisers should be getting together sometime in the near future and will be reviewing the waiting list at that point.
