I have to say Chris, hats off for attempting this. As one of the few female gamers (who doesnt hide the fact), I have to say one of the main reasons for joining Mygaming was the people on here. I have been on a fair few forums where once it gets out that your female, their attitudes change.
But I also have to admit, I am maybe one of a handful of women, who prefer to play with the guys, but then again I really don't know that many female gamers. I might not be a hard core BF3 player, but I do game for the fun of it. Making friends along the way is always a bonus.
Overall it depends on my attitude - if a girl acts all flirty and silly, they wont get any respect. Respect the group of people you are gaming with and there should be no issues. If there are issues, please dear lord dont run to the first admin you see! Try to sort it out via pm or email or even skype (I have done that once). The thing to remember is we are all part of one big community of gamers, whether we all play the same thing or not.
Besides in 99% of the games there are ways of ignoring the idiots
