sterlingmemory: only because sterling_memories wouldn't fit in it's place. Every forum I go to, it's one of these forms.
Anyway, sterling-because it is my last name while playing on stage, recording, nickname, etc.... and memories/memory- because I'm a huge Dream Theater fan and one of the albumns is titled "Metropolis Pt.2-Scenes From A Memory". Hence, sterlingmemory.
And I know that no one else uses it....hopefully.
