Answering my follow-up question: I was able to override the bbpress.css styles by adding a css folder to my theme and copying the bbpress.css file into that for editing.
A quick follow-up question. I’ve already found that the clear: both; rule in the bbpress.css file conflicts with my theme. I’ll need to override that. If I make changes in that file, will they be overwritten in an update? Is there a place to override styles elsewhere from within my theme?
Thanks, natweb. This already looks a lot better, though I’ll be styling for a bit. At least now it’s coming up only as one list of forums instead of over 200! Hopefully this will make things less painful!
