At one point I kept a list to try and cross reference names with handles, mostly to see who was posting photos (since those often have real names, not handles).  Since most didn't correlate much with real names, I guess we're 'creative'. 
Personally I dont' like mine so much and I've thought about changing it, but that would just be confusing.
I like the way we tend to abbreviate our handles too!  Like KF, MP, PJ.  Maybe we should all have 2 initial handles.  :)
