Welcome to APAT Sean, I"m sure you"re going to enjoy the experience.
Dates for season 3 have not yet been announced. With the final event of season 2 being at the start of November, I can"t imagine season 3 starting before January 2009 - although I have been wrong many times before
I suspect dates will be announced during November or early December.
Season 3 consisted of 2 team events, both of which were live - a forum challenge held in Blackpool in July, and the International challenge which will be held in Brighton in November. I"m not aware of any team events held online.
Season 2 was the first season in which Regional events took place, and was a season of tweaking. The Regional venues for season 3 have not yet been announced, but I"m assuming that the procedure for playing will be the same as at the close of season 2. Basically, players were able to contact the casino/card room from 7 days prior to the event and pre-register. These players were given a time, on the day of the event, by which payment of the entry fee had to be paid, otherwise "their seat" would be available for purchase by players turning up on the day.
In season 2 there were 3 ways to enter a National:
1. Qualifying via a Regional event
2. Qualifying via an online event
3. Direct buy in (clickfest) via the website
You can play a National without playing a Regional event.
Hope this helps you. If you have any other questions you"ll find the folk on this forum all too willing to answer them.
