Like flygunz, I have taught quite a few females in the RW environment. Also like him, my best ever stude was a female - but then so was my worst!
Truly, the dinosaur attitudes are getting fewer and rarer. Anyway, aren't all studes worthless until they produce incontravertible evidence to the contrary?
Go for it - better than looking over your shoulder in 10 or 20 years asking 'what if?'
