I just tried to register for the 12a $1 + $.10 tourney on Bet21, and got the message that it's an exclusive tournament. I know this happened when UB first started, so I guess it's no surprise. However, this tournament has a higher than usual payout with low buy-in's. I sent them an email stating what a disservice it was to customers not to get it fixed. We'll see what happens. This is really a disappointment.
When did you try? See swog's note reference times tables open. I think they have changed their software to only open the tables for an hour just before the tournament starts like they do in Poker. That seems to make sense, because all the other tournaments now show "announced" versus "open". The only site with tables open all the time still is UBT. Hope that helps.
It shows open and I just went back and tried again. It let me in this time. Looks like they got it fixed in lightning speed.
