I'm not a veteran but want to reply anyway, with my experience.
When I first came, Eluvatar was WAD and everything was amazing and wonderful and new for me. I'd never been active in a feeder before and sort of fell in love with TNP. Which means my life was rather sad, 'cause you are supposed to fall in love with people and not with dated browser games. Or TV shows. My English sucked like a thousand times more than it does now and TNP was kind of my English teacher... And many other things. I guess. Maybe.
So Eluvatar has a special place for me in the WAD hall of fame.
But... McMasterdonia came in like a wreeeeecking ball!!! he's just the best ever. Ever. On Earth.
