I haven't been here very long but I can say everyone seems to get along well and up to yet I have had no issues
I do express my femininity, how ever when I first joined the online fandom the majority of its members were in fact women.
It was very rare to see a man and when you did he was often another members husband who had also grown to like ponies. There was no pegasister/brony identifications either, we were all just fans of MLP.
For me coming back after my break to a predominantly male fandom is strange but I like it that it has become more diverse.
As for contribution I used to do a lot of custom ponies and art work so I'm hoping to get back into that on a regular basis, although I'm finding it harder to get baits than I used to.
