I think it's safe to say that they're right.
We're in 4 countries with a million and change active members.
As for contacting corporate, they've been very swamped with new changes in WPTAPL as well as with changes within the WPT itself. If you contacted them via email I do know that some email programs were placing their email in the SPAM folder.
There is a number you can call to speak to memberservices (316) 689-0600
Maybe I can help though. I'm a League owner with them.

Wait, you confused me. When you mentioned APL, I thought you were shortening our name. We used to be called the APL and as far as I'm aware, still hold the trademark. Hmm, might need to talk to someone about this one.
Sorry to confuse. I was talking about our league. The World Poker Tour Amateur Poker League
TM. The official amateur league of the World Poker Tour.
