You think with too much haste. Should we have sign-ups now? The tournament has to have enough interest in it for this to have a point. This topic is to generate that interest. Divisions would be pointless as the numbers are still too small.
Anyway, like someone said in this topic if they did or not, having the tournament on one day would be impossible due to scheduling conflicts, timezone differences, recording of the matches, and it would just be stupid in that the whole thing would be over too quickly. It would be better to have as many things as possible possibly. Like one main tournament, some warm-up matches, and maybe a multiman contest to see who can take out the most computer players.
