Vormulak and Death have a lot of posts but thats due to them arguing. I can't say who influences the forums the most because it depends on your definition. CORP as a whole deserve mention, they always on the forums.
Genghis as king of the off-topic
Aranka as queen of the general forum
Richard Sharpe as leader of the Help forum
Belgian Gentleman as honourable coach of the map-development
Master of Desaster as master of the ladder forum
ChrisCMU as reputated knight of the CLOT development forum
Pooncrew as captain of the Clan forum
I saw this and I agree with most of them, although I've never seen Richard and Aranka use the forums and Pooncrew you can't really count because all he does is spam the forum with his clan's shit.
I would also make 2 more recommendations and that is Death for his forum games, Knyte/Math Wolf for the beautiful statistics, Great Expense for the clan league graphs and of course the creator of Warlight himself, Muli.
So mine would be:
Genghis as king of the off-topic
Cata Cauda as supreme cat of the general forum
TBest as leader of the Help forum
Belgian Gentleman as honourable coach of the map-development
Master of Desaster as master of the ladder forum
ChrisCMU as reputated knight of the CLOT development forum
Death as Pro-gamer of forum game making
Knyte/Math Wolf as the great nerds of the forum
Muli as the King of Dashboard and making this shitty setup more enjoyable
Edit: Forgot about Muli
