Ap is a little slow with the pay outs. They are very slow with the customer service as well. They usually respond to e-mails a few days after you forgot what your problem with them was.
As for withdrawing they are one of those sites with a $50 minimum. I have been told that it is also one of the rare few that do not require an initial deposit to withdraw winnings earned. Whether it be from transfers or freerolls
I don't know for sure on that. I deposited there as I usually do at any site I play at. I usually check them out with freeroll or two first.
Couple things I will suggest if you have not already played at AP and are considering it:
Watch your bankroll. Accounts have been compromised there before. I know of a few incidents where it was an AP staff member that was behind it. Never as is with anything ever give your pw to anyone.
Expect extremely loose play at all levels. I've played as high as 5/10 NL cash tables and bought into some meaty tourneys. There is extreme loose play, that tends to get rewarded. There will also be a lot of hands you will be in where more than three players will have a premium hand. I know I know it happens live and at other sites too. It happens A LOT and I stress A LOT at AP.
There are multiple skins on the AP network. There are soon going to be more after the UB/AP merger is finalized. People can and have been able to log in multiple accounts simultaneously from different skins. This isn't unique to their network as I have seen it other places as well. If you suspect that it is happening I suggest you leave that table after taking a snapshot and report it.
