Yes, I noticed the regulars and their banter and felt a bit as though I was intruding but at least there are no in-jokes! Quite different from US outdoor forums. Apart from Kate, I didn't notice any other female regulars and not sure if they are as rare as hen's teeth or don't do the banter stuff.
I contributed a couple of things but felt that my experience of tramping/climbing in New Zealand is probably a bit irrelevant aside from comments on gear being discussed. A lot of our terrain is very remote e.g. on a 54 day south north traverse with another woman, I spent 32 days of it seeing no tracks, no folks and 1 cairn with no other artifacts of human origin.
