Well your ranking is based on your activity. The more you post, you comment, you help around, etc,... you will get ranks for them. Obv if you post a lot but only say 'lol' pbly you wont. When OneHandLuke does his ranks up for members (every other week), he looks at posts and activity on the forum. The more you contribute and are active, the more you will get ranks from him. After there is the part you get noticed for helping and being active on TS or in a particular section. Officers can suggest a promotion for you and generals and higher can promote you on the spot.
Annnnd then there is me, with the recruiting, but pbly one of the easiest way to ranks up: 2 recruits=1 rank, up to SMA max (which is the highest you can get without being an officer)
But no worry, we try to check everything we do, obv we are human so mistake can happens. But in your case, its just how the system works about recruiting. You werent taking credit for anything more than what i had already about it. Go with peace in mind, so far you are doing a great job
oh and btw, i should had say it long ago, but i kinda enjoy your avatar/profile pic. As much as i wasnt really a fan of him, as much as it makes me smile, good memories
