Creativity needed!

So, I have two online communities that I LOVE! One is Fertile Thoughts. We have a thread I've been on for almost two years now and I got amazing advice from starting to try to get pregnant all the way through today. Love those ladies on there!!!

More recently, I've also been on Twiniversity. Great advice for Mothers (or parents) of Multiples. They have a ton of dicussion and, by reading the dicussions, I pick up a ton of great mom advice (not just twin specific).

The one thing I've noticed is that there is no similar community I can find for LGBT (lesbian, gay, bisexual, transgender) families. Most of it will be general parenting discussions I am sure, but there are also a lot of challenges faced as an LGBT family that I think warrants some support and lively discussion.

So...My next endeavour is to start such a group! (Or, if I'm mistaken and there already is one, let me know!). I just have a few questions -

1 - Should it be the whole LGBT community or are the concerns different enough that there should be a lesbian group, gay dads group, etc
2 - What in the world should I name it?!?
3 - How do I find enough members to make it interesting and helpful enough for all of the members out there?

Would love your input whether you are part of the LGBT community or not! Thanks in advance!
