how many of you actually pay attention to them? i was thinking about changing mine to something i read in my photo history book the other night and then i got to thinking "how often do i pay any attention to what people use as their signature?" and i decided it's maybe 50% of the time. every once in a while one of them catches my attention and i look it over. but you know what? the only one that sticks out in my mind is goodluk2u's. and all it says is "monkey." so for those of you who DO pay attention, do you have a favorite? (other than your own.) are there any you don't understand or that you have questions about?
