I'm thinking of writing up a web app that'll let people write Song Fight reviews, and it'll format them for the forum, optionally with a pretty coloured star rating and other fancy things people might suggest.
Being the standards nub that I am, I'm tossing around the idea that I could encode the reviews within the <a href="http://microformats.org/wiki/hreview">hReview</a> microformat. Only issue with that is that I'd need the <p> HTML tag enabled.
I suppose what I'm asking, is that likely to happen? Because I can always just not make them hReviews -- it'd just be a lot cooler.
Something to consider: phpBB allows members to individually disable HTML in their own view, regardless of the system-wide setting. So if consistent presentation is important, you probably want to stick with BBCode (or do it on a separate site.)
