Just do what I did, and be totally unoriginal and use a name generator.
In fact, use the ->one<- I did. I mean, it gives you the coolest ones in the world. Genius Lynx and Jockstrap Brine-Shrimp! If you can guess who's codename the latter one is, make sure to call them that. XD
Oh, and as long as people can tell who you are and not confuse you with eight thousand others, you're doing fine.
