My name is Mike.  Many know that now.  I usually have a signature or manually sign forum posts with Mike.  I try to register all forums and stuff with mrodgers.  From now knowing my first name of Mike, you can figure out my last name is Rodgers.  I am registered at LFS, LFS forum, theuspits, superspeedway.com, wspilots, avsim, CRC, RCGroups, RCUniverse, Wattsflyer.com, and many others as mrodgers.  If I can't use mrodgers, I stick an 88 at the end because my first internet login experience, mrodgers was taken, so I stuck 88 on the end.  Why?  I use to have an 88 Toyota 4Runner and I was joining a Toyota 4x4 internet mailing list.  I use NightHawk|CRC as a nickname in LFS.  It comes from my bike, an 83 Honda Nighthawk.  I sold the bike and someone on the servers the other night said "now you have to change your name."  So I changed it to non-NightHawk|CRC for a little laugh (yea, just a little one).  I forgot about it and it was still non-NightHawk|CRC last night.
 
No point really in all that.  I use my real name in almost everything I register for.  It's real easy for me to type quickly.  The nicknames are interesting and I like them.  It's easier to remember most of who I race with when the names are Banshee, th84, Turbo-Love, Cropsy, Tweak, Marsh2a, etc.  But if it were Joe, Brian, Jim, John, Paul, and Henry, then it may be more difficult to remember who is who.
