There are no "last minute changes" really. Brackets will be created just before the tournament begins and those brackets are final. If someone is late or something, he won't be able to join the tournament.
Actually, as long as sign in is done manually in the chat by the TOs, last minute changes
will be need. Not because people are late, but because mistakes happen.
I don't think more than one or two of the tourneys so far has gotten started without someone being forgotten. See how cisco had to hax in frostfox here (
http://elementscommunity.org/forum/index.php/topic,3449.0.html), for example.
The main screen isn't critical to begin with. We could have the most recent tourney showing, with a "start new" button or something.
Currently we have 8-32 players, and as long as we're doing manual sign in that's probably the limit of what will work.
If / when we get an automated sign in, that could perhaps be expanded to 64, but I don't think we've had more than 20 players in any event yet so it's not a priority.
If / when we get an automated sign up, once the regular slots are filled, the "(as reserve)" box should be checked by default and disabled (or there could be an error msg, if that's easier).
