Hi gennee,
As it says on the details page, "You'll get your own account on our blog with full privileges to post whenever you want, about any LGBT-related topic you choose."
As long as it's LGBT-related then there's no problem. You just have to be able to post quite regularly. You don't have to post just about transgender topics either. Anyone can report on something in the news if they're stuck for topic ideas. We do like to post from personal experience sometimes. Our site is aimed towards people who are questioning/coming out. Personal experiences are helpful to them (no matter how dramatic or dull) and they can often be useful to reassure them if they find they're in a similar situation.
I hope we'll hear from you soon!

Best wishes,
Patrick
