Easily integrated forum?

[smatts9]

Is there any forums out there that I could easily integrate an already made user management system?

I have programmed my whole site from scratch, but I am running out of time to work on the site and to make to forums would take too long. Is there any forums that I can easily manipulate to use my user base, or would it be easier to make my own?

It would probalbly be easier to make your own since you would need to know the coding style of the forum software you're working with and you would have to heavily mod it. I would make your own, it shouldn't take too long since you already have the user part set up.
