haha this sounds fun but i think itd be a bad idea to have mods regulate what counted as significant enough to level up. itd be a lot of work to manage because youd have to read so many threads. it might work for a small game of like 25 players though

better to make the levels increase after a flat number of threads (more for network posts, fewer for log posts. slap on a minimum length like 10 comments for first and 5 comments for the second), maybe an evolution system
