Introduce more of those titles (i.e. Moderator, Super Moderator, etc.)
There are members of the community whose contributions in certain areas are beyond all others and they deserve a title
For instance:
D94 has successfully established one of the largest publically available raw marks databases and transformed it into a nice website
dan964 has the largest collection of past papers from different schools and has organised it conveniently, perhaps the name HSC Resource Manager?
InteGrand contributes heavily to the maths and science forums
Not sure if this has been put forward before but what do you think?
I feel as if it wouldn't be favourtism since most of members of the community would agree that people like the aforementioned three have made outstanding contributions and deserve recognition
