ranks

Good posts, frequent good posts, being a memb that follows by the rules.
I think theres more but i cant think of them,

aswell as taking part in RPG's

yeah i think you get something like 5 rank posts if you kill someone and one rank point if you get killed

there is no "set" way of getting points from rpg's, the mods give you what they are comfortable with or what you deserve. You also dont get them right away, I wouldnt suggest pestering the mods for points after an rpg or after being here awhile.

There was going to be a set point ranking for rpg's but that was thrown out with Bug-Hunt's
RPG Dice idea.

one other way is to be a clan leader as in eleceted promted you get promted to rank 50 right off the bat

You do get bumped by becoming a clan leader, but it isnt always 50. Kidd went to 70 something when he became leader of AD.
That is one 'set way' i guess, but becoming a leader doesnt happen often, and they wont just pick anyone from the clan, you must be recommended/picked by leader, or voted by clan. I am just saying the opportunity doesnt come up very often.
