Majoraty does not necessarily rule. It is the administrators', not the users', choice. I voted No, because I believe they make the board crowded and force the board to make more queries (it is called something like that.)

Avatars just would not look good. They make a board look unprofessional and waste space that could be used for actual content as opposed to a picture. There have been many topics like this before, and none of them have actually worked. My opinion is that custom titles are enough and that avatars make the board look crowded and unprofessional.
