-Put yourself in your avatar.
-Don't put some bodybuilder or athlete you worship
Funny pics such as Family Guy and other comical characters, unique portraits, and plain cool pics are still ok.
Point is that there are too many people posting on here with no pics of themselves to show what level of knowledge and work ethic they have. Anybody can remember some study and copy and paste it and try to argue their point. I just find it annoying and kinda childish to put some IBBF Pro in your avatar.
If you want to have an avatar that is not a pic of yourself you must:
-Post some pics or videos in your hub
-Have a history on here, be grandfathered in, and deemed cool enough
-Not argue any point made by someone with a valid pic/vid
Props to H4M, MM, Stu, Way, and everybody who actually walks the walk and not just type the talk. If you're ashamed of your physique this will be motivation to change.
