So after 50 min of planing I devised an idea for our ranks. Basicly a link on our group will be put to a blog that shows current memebers and thier ranks. Next to each name there will be a crown. There are two methods:
1: If large scale drawings are made a single crwon will be put and i will add all the names of that group. Like there are kings, a crown for kings, then all kings next to thet pic.
2: You can make sprites of crwons. they will sit next to the group memebers.

*If you would like, you can sugest a symbol for other ranks like court jester or dirt
**Crowns are for royals. the rest are just symbols
*** Prince: a small crown Princess: Tiara.
