Well... The way I see it is the shorter the better, more recognizable. I see people in this community like Orko who everyone remember because it's not a difficult task to remember 4 letters where if someone went around the community with the name 14Bulld0G45 your not going to give a shit whether there the best TB player ever or not they have an irritatingly difficult to recognize name and your going to go out of your way to cause grievous bodily harm to them... or maybe just not acknowledge them.
And if this doesn't make any sense and you think I'm chatting shit then please let me know. Thank you chaps!
