I think it should be easier for library creators in Quest.

In the TA/GB selection, there should be a new choice: Text Adventure Library. Choosing that guides you to the TA creation GUI where you can create away.

And since there's a gamebook mode, we could even have a Gamebook library!

Sounds good Sonic. Why not add it to the suggestions http://quest.uservoice.com/forums/34461-general section?
