What is the best platform and approach to creating a basic stand-alone discussion forum?
By "stand-alone" I mean a forum that is not associated with a particular website. Obviously the forum would need its own unique URL but it does not need an associated or separate landing/web page.
I've looked at a couple of places like WordPress, Blogger, Blogspot, etc, but their main focus seems to be blogs. I haven't spent a lot of times on blogs but they seem to be structured chronologically (ie showing a list of dates) rather than by topics.
I am really just looking for a simple way to enable someone to post a question/comment to start a thread where others can respond.
