The site is not available to players in the USA, so if you are from the US you can't join.
Now I feel bad if you are from the US...
If you aren't from the USA read on:
There is info and stuff to print out for each of the game types - even software for Sit and Go's - that is all free from the beginning, so even if you signed up just for that it would be valuable.
You just need to sign up with a site in order to gain access to more articles. And you can't access certain articles until you win certain amounts of money. They really coach you along that way.
The forum is very active there also, mostly Europeans however.
Hey, I just thought I would let you know about a site that I found. It's called PokerStrategy.com
No offense to the Poker Professor but I think this course I found is far, far superior. They have courses on FL, NL Big Stack, NL Short Stack and also Sit and Go's. The material that I have printed out is amazing, top notch. They even have videos on a lot of the material.
The only catch though is that you have to sign up for a site in an account that's linked with them. PokerStars is a site linked with them, but only can be linked on new accounts, not existing ones, so I had to join Full Tilt and consequently now have accounts on both sites. But if you pass their quiz they give you $50 free starting money.
It's up to you but I thought I'd let you know as you have been a great school mate here.
Good luck at the tables!

PS: You'll still find me here too, because both courses combined will really help.
