I know the basics

Like is there anyway to possibly send the information from my registration form, the username and password and it sends it also to pnb_users so that the same information can be used to login into the forum?

I looked into the register.php but what am I suppose to change? How do I go about doing that?

It's just a regular site with its own registration and login that I created myself, I not using wordpress etc.

I have a website where I already have my own registration and login. I wanted to know how to be able to for example: The user can use the same login information from the website to also log in to the forum. Without having to register twice which can be annoying for someone. So I want someone to be able to log into the forum using the same login info they have from the site and not need to register in the punBB forum since they already registered to the site anyway.

Can someone please explain this to me in detail. I've looked around the forum and didn't find anything to what I was looking for, or it was never resolved.

Please help me with this,

Thanks
