For card collecting I am mostly about Baseball and Football I prefer vintage before 1990. It is still difficult for me to consider the 1980s "Vintage"but they are heck even the 1990s are now considered vintage and soon the early 2000s. For hockey and basketball I am basically only about The Washington Teams. I also collect some Non-Sport but am a bit picky about the themes.
For most card sites I am CaptKirk42 (often just all lowercase) sometimes I use my email name "klandersen" sometimes with "42" added at the end.
