Just a suggestion but it could be
Newbie = 0
Jr Member = 50 and minimum 10h
Full Member = 200 and minimum 40h
Sr. Member = 500 and minimum 100h
Hero Member = 1000 and minimum 200h
If you dont put minimum hour, you will get member that will spam topic just to get higher level.
The level on bitcointalk is really important and Im sure we should aim for something similar.
Is there a trust system ?
Agreed, we can rise the number of posts required for the ranks, will fix up something higher than it is already and more close
to the one you just shared.
About the logged Hours, we will add a medals system for those so there is no reason to mix them in my opinion as spam gets deleted as well.
About the trust system, at the moment there is a basic one implemented where you can give trust up or down to any member,
will be changing it to implement one like the one btct has, so users can be familiarized with it and so it can save history of the trust reports, just like it does on btct.
