Try keeping tabs in your signature line at the bottom of your posts. Click on the white "Control Panel" on the grey background. You will have to scroll down to the large, white box to type info. You can type in what ever you want. Maybe separate them out like XX Grackles, XX blackbirds, XX ground squirrels, etc. WadeS and I, as well as others, have done that. Look on my signature line if you want to see what it looks like.
WadeS and I are shooting for 1000 air rifle kills in calander year 2010. We're each 400+ now.
