people that do stuff worth remembering, are generally remembered.
Doing a moderation job assigned to you very well is not an exceptional work. Probably a lot of people can do the job just as good as you. Legends, however, have pulled off things only a select few in the community can do. So, while your contributions and time are appreciated, there are people who are better fitted to receive recognition.
Like I said a few days ago in a RT board thread, if there is someone who is well deserving for his contributions, he will be noticed by the legend council. That applies to both the present and the past. Right now, I am quite certain they already covered pretty much everyone in the past who deserved being a legend.
Anyone dan do it, yes, but there are also a lot of people that can be game masters, market squad, etc. There is a difference from being able to do something, and actualy doing it.
