Add Badges. (when I say badges I mean you can name them anything) For example if your id is lower than 10,000 you get a badge or if your accounts more than a year old you get a badge. Basically a reward system but you get nothing. The badges can be seen at you profile. Thats all :P

sounds cool

why lower then 10.000 tho? thats a bit much

Well like goals like 100 1,000 10,000 for badges
