I've played my games up through round 3 (well, also am stuck at round 2 with BigBlue since he hasn't been on too much lately) and have tried moving onto the next rounds, but my round 4 and round 5 opponents haven't answered. If you're too busy, that's probably it since my round 7 opponent is DarthFerret and he hasn't been on either.
On the whole, with all of these absences, I think the BYOS format is pretty dead anyway... along with BigBlue, DF, and seemingly Ransac, Modus is busy with his pro career.
