I'm am on the search for a good PHP forum script online. By good, I mean it should have common basic communication features such as private messaging, quoting, and maybe subforums. Any recommendations?
I'm also looking for a forum that can integrate into a blogging platform or has clean globals of which I can develop my own for integrated user bases. I know there are many strategies for making something like this happen such as what Icrontic is doing now with, I presume, separate user bases and synchronous article commenting.
