1) I don't see a huge benefit in separating mixed and f/f content. Speaking as someone who isn't into femdom mixed action, naturally around 80% of the pictures/videos/fiction I encounter here isn't material I'm interested in. On that basis, much more of my time is potentially 'wasted' than someone that is only into mixed action who occasionally finds some f/f content. But I don't consider it a waste of time at all. It only takes a few seconds for me see if something is mixed, and then I move on to the next post/thread until I find something that is of interest to me.
And even although I have no interest in femdom mixed wrestling, it's obviously the predominant style in this fetish and so I do inevitably encounter many mixed wrestling/fighting pictures/videos as I surf the net on a general basis, which I'll then happily share with those that are interested in it - even though I myself am not interested - and I know that others here do the same. If the forum was split however, we'd lose some of that potential exchange of information, as some posters would only ever visit one section of the forum.
Also, separating some of the more 'general' picture threads (such as victory poses, schoolgirl pins, etc) would also mean generating twice as many threads.
2) This one I do agree with completely. Although male-dom action is the only mixed fighting that interests me personally, I'm very much aware that for many F/M fans, it is something they never want to see. As such, I think it's right that any content of that nature should stay in the threads already in place that are clearly marked as containing that material - and if any subsequent threads were started, they should obviously be clearly labelled 'Male-Dom' or 'Male Wins'
