hellooo webmaster-talk!!!
I need to know how to make a simple register form witch send the registration info to a MySQL database.
I have a simple 1 page register forum, but i think it would suit my site better with a 2 page form.

Hellooo
What exactly do you mean by a "1 page register forum" and "2 page form"? Should the registration be some kind of a two step process? Try to describe a scenario of when a user registers, what pages loads and what the user does etc.

There are many free scripts, just search in google
