They did not mention to me anything else than having a client and an escort to write articles from their different perspectives. They asked me what I wanted to write about in my first article, and they liked my choice. They are very open to suggestions. They did not mention anything about Trans professionals, but I think you would bring a unique perspective, I bet one of my balls (after all, I don't need more than one) they would take you in a blink.
Contact them and offer your talents, you can mention me. Anyway, I am sure they are following this thread.
