I have been reading with utter fascination the usernames people choose, and I would love to hear the stories as to why people chose them and for some of them, what they mean! Even if yours seems fairly obvious, do tell why you picked it anyway.
Mine is fairly obvious, but here is the story behind it... I've been a fan of Jimmy's since I was 8 and have always been called various nicknames involving Jimmy, but one year I happened to be in a drama production cast as an angel, so of course owing to Jimmy's 'angel with a broken wing' comment, I picked up the tag Page's Angel, which has stuck since then. Somewhere along the line the 's dropped off, hence PageAngel.
So there you are - anyone else care to share?
