I'm working on a new website (as a hobby with the hope it will make some money) and would like to offer a forum.
I'm using WordPress and hosting it with Dreamhost. How would I integrate a forum with my website? Should I host it on a different database to that the website's on? Can you recommend any free, easy-to-use software that I can install on my host server?
Any help/advice appreciated. I'm only just getting into this side of things, so any or all of my questions might seem daft - please explain in appropriate level!
