Previous posters, lurkers, or ladies who I've seen post once or twice but aren't regular posters:
CougWife817
Mrs_BigD
Sammygirl
HandyMom
Mrs FMcoug (pwned FMcoug in a classic CB post circa 2007 I believe)
MrsFunk
Sasy (P-Widdy's wife)
angeleyes
TNT's Fiance (she may be imaginary, but hey, so's 50% of CB)
I also know some other women who lurk but don't post. Can't imagine why, CB is such a warm, fuzzy place for women to come feel appreciated (though according to some that applies regardless of gender). I'm sure there are some ladies who post on non-gender specific topics only and thus fly under the radar...kudos to them, if you have good info to share, shouldn't really matter.
Apologies to any female posters I missed!
(Edited to add more I've found as I've read past posts)
