Here's some things I can think of off the top of my head that might end up in a subforum...
Defining gray-A
Defining demisexuality
How to tell if you are gray/demi - and not ace or sexual
What exactly is sexual attraction like for a gray/demi and does it differ from a sexual's sexual attraction in any way
"Coming out" as a gray - is it important? How to do it?
Visibility for grays and cooperating with aces and other groups
Where do we fit in the spectrum - "levels" of grayness
Dealing with "boundaries" - understanding a gray has limits, where they are - not necessarily just in relationships (ie, limits with libido, sexual attraction, etc)
Explaining grayness to sexuals and that it's not full sexuality and why
Explaining grayness to asexuals and how it's not really all that sexual
Helping repulsed grays who want to try to work past it to be comfier with themselves
Helping people feel that it's "okay to be gray" and they don't need to be perfectly ace or perfectly sexual
How do we fit in with the LGBT (since asexuals worry about this a lot, is it "easier" for grays?)
