Well what good news that is! I'm two for two female on the Craigslist four spider deal. Yes, she is certainly far from mature. I didn't take that into account since I've only ever looked at mature females.
So there is a difference of opinion. Does anyone else care to chime in with their opinion? I'd really like to have a consensus, and I'd really like to have some confidence in my ability to sex these guys/gals in future!
