help to connect forum smf to pvpgn

I guess a good solution will be make a trigger in MySQL that executes on a user registration on both sides (pvpgn and smf, two triggers in their tables with accounts) or restrict it by one side only. But here may be a little problem with a password (cause it hashed).

Another way is to modify the smf registration function to create the same account in pvpgn database. Next disable registration inside pvpgn and allow it from a web registration script. Then make modifications in the web script to create the same account in the smf database.
