Yeah true, but do you see famous clans with ranks ingame?
Many clans that have rankings do not show them ingame.
Btw i think the [Nub] tag should be compulsory for all new members then after that they can choose to have their rank shown or choose to have just [SFST] as their tag.
Another point about the ranking system is the requirements to rank up, for people who may be .... lacking judo skills but may be exceptional in other 'approved' mods should be able to choose their own best mods instead of having to always do the Judo, kickboxing thing.
