Step 1. Look at number of people online, if it’s lower than 15, then them forums dead as hell.
Step 2. Look at off topic, if there’s less than 30 new topics per day, then them forums dead as hell.
Step 3. Look at the recent posts on the right, if THE FIRST 4+ ARE THE SAME FUCKING PERSON, THEN THEM FORUMS DEAD AS HELL.
Step 4. (Reviving the forums) You can’t. You must wait for TGR or walk with the dead.
