That means that in the last five months (slightly less, actually), its gained over a 1000 threads, almost 33000 posts, and close to 500 members. That's an increase of about 6.2% growth in threads, 8.3% in posts, and and a whopping 15.3% growth in members, in just five months (very good stats for a site the size of theRPGsite).
