it means I've goofed. I discussed numbers with Tony and others, and put a figure of 90 on it. This was bravado on my part. I thought that we would struggle to get 90. I sent out the mailing (which now goes to 937 addresses) at the end of last week (having not troubled to do so last month, or the month before, because we were full up) and the registrations have been pouring in. The mailing went out with a pdf which was kind of nice...but it might have been too nice.
Turning people away isn't great. And, given that it's been rising by about ten a day, there could be a lot more. I'll make room for old-timers, but there are going to be people who are disappointed, and may not be back again.
