How the others said, you have to do something for the community to be remembered. Sweex for example and Lagekilla (did i spelled it good?) are legends because they are the best replay makers ever in toribash so far. Solax is a legend because is a very old staff member and one of the best Admins here for long time so he obviously did good things for the community, phail also was a MSquad for very long time, he is also SMod so.

You have to do important things to be remembered in the future, that's why they are called LEGENDS.
