If someone is up to this challenge

I am using E-Blah as my forum on my  RPG game.  What I would like is to be able to call a script that uses the pre register function of E-Blah and passes thier charactername,password & e-mail to "pre register" them automatically into E-Blah.  That way when they create thier character in my game, it also creates an account with E-Blah.  Then, they can go into E-Blah and update thier info when they want to use the forum.

In my confirmation e-mail my game sends, I can send the information that they pre-registered and need to fill out the rest of the information on thier time.

Hope this is clear enough (not enough coffee yet this morning!)  

Thank you.
