>>he forum URLs were the only URLs NOT to be affected
Well, if you assume that Panda was all about engagement metrics, the forum was likely the best-performing part of the site.
In general, I'd expect forums to score well - high repeat visits, lots of direct navigation, long time on site, high pageviews per visit, etc. I wonder what the problem was with the forums that DID suffer under Panda.
