I'd still like to get something like a head count. Will that be possible by watching the Journal?
I may be wrong, but until you mentioned it, I don't believe it was even considered!
It was easier in previous years as the Megameet was much more associated with TMA, but most attendees now don't use TMA as much as they used to, and due to the ridiculous and blatant thread subversions by jealous parties over the last few years it wasn't seen as a priority to plug it here. If people wish to state their intention to attend, then that's great. We can ask people to respond on the Journal and Facebook and Twitter as well, I guess, but I don't believe there was ever an intention to publish projected numbers prior to the event... It's more often something we only know (and are pleasantly surprised by!) on the day!
