Fencer: emmett's request sound good, but I would prefer a complete filter builder, even if we have to wait longer for it. Otherwise we will end with a lot of separate requests, like :
1) Filtering by a range of time control
2) Filtering by vacation / no vacation
3) Filtering by week-end days / no week-end days
4) Filtering out Fischer time controls
5) Filtering out games without autopass
6) Filtering by match type
7) Filtering all but random colour games

Well, basically, every create game option could lead to a filter. Personally, I would probably use at least 1, 2, 3 and 5.
