No worries. I think new people to the site aren't able to do visitor messages until they become a "Citizen" (after getting 25 posts, and I believe sending something in to say, "Hey I want to be a citizen." or something like that. (It's been a coon's age since I joined, and I am a bit fuzzy on the details. I know there's a thread in the intro that has all that good stuff).
I'm open to talk about the Blue Ajah and field any questions you may have about our group here (or direct you to the right person if applicable).
I know an easy way to get up to 25 posts is to post a "welcome" in the introduction thread, find an active enough thread you like and start posting.
Hello again! I'm glad to know that you use the Library - it is a great resource! I might not be able to answer all your questions, because my role as Editor is not for the Library, it is for our monthly newsletter, the Tar Valon Times. Still, I'll answer what I can and anything I don't know I can find out for you.
