I didn't log off, I got DCed just like Svarvsven earlier and due to issues with the login system, I couln't log back in, just like he couldn't.
The problem was not just with WoW's login servers, but also with that of Starcraft's login servers.
Anyway, the event went pretty well, indeed, thanks. Could have gone a little smoother, but I think I did quite alright for organizing and leading my first little event.
