Maybe we should give the ranks with trust (Full, Senior, Hero, Legendary) only for members which persons are well identified through documents or i.e through eyewitnesses - which eyewitnesses are identified well already.
Absolutely not:
I'll get right on that, just as soon as hell freezes over.
I think, it would be better. i.e. Full Member the highest rank, because this member has a connection to the jurisdiction of our world.
If somebody won't want to be identified - remains simple Member. If a rank has no connection with the meanings of "Legendary", "Hero", "Senior", then it would be more better to exchange this ranks to Member or Full Member.
