It would be fun to have some form of event, even if it is more limited in scope than what we used to see in QExpo. I'd be interested in working (a little) on one or two small projects I have.
From the look of this and Celephais's forum, it does not look like anyone is ready to shoulder organisation. I'm unfortunately too busy in both my professional and personal life to really be able to help much.
It would be nice, I think, if - whatever ends up being decided - the "event" (even a small one) happens during a defined period of time. Releases spread over the whole year will get extremely little coverage and the lack of a deadline will mean most people won't be able to get motivated to get anything done mod-, engine- or map-wise
One could maybe imagine an (weeklong?) event in the form of a Facebook group which people (who might have to get clearance first) could post their own news on? The facebook page could be set up quickly and be used for people to simply chat and discuss their project (possibly months) prior to the "event," then (hopefully) a few more special things could happen during it (besides news of map/mod release and such), like online matches, or Twitch videos? The main organizational burden for the site itself would be to keep an eye on posters and posts, make sure things don't get out of control, and give clearance to the right people. Individuals will be free to set up their own sub-event (say, like a speedmodding session, for example) and make an announcement about it. Nothing will be actually "hosted" on Facebook, which is a little sad, but it's better than no site at all...
I mentioned Facebook, but you guys might know of better sites.
