Not a mod (yet) but I can answer these, as I'm the one who started the name change thread. It's not THAT hard to change it, they just have to get verification from you and remind you to log in with the new name next time you log in. We are limited to one name change so people don't constantly change names. You wouldn't be able to recognize anyone. If I was bob tomorrow, and then KSPFreak the next, and then THISISSPARTA the next day, you would have no idea who I am. We're limited to keep our sense of identity with our usernames.
