Re: An alternative to sub-forums?
ear1grey, I concur.
I’m already using tags like WP “categories” as they are the most easy-to-use feature of bbPress (thanks, AJAX), and quite analogous to what we call “forums” anyway. After all, we’re just talking about context really, and tags achieve that easily.
My only real complaint is that the word “tag” is so generic it ends up meaning many things and nothing all at the same time – category is a much better “tag” for “tag”.
