As for GA5, that is Nicholas' department.
I wondered if you had an adventure already written and submitted for the next issue (assuming there is one, of course).
If you're looking for more ideas on what to write on in your copious free time, I just finished a rather interesting, and different, supplement:
http://www.rpgnow.com/product/166568/Ed-Greenwood-Presents-Elminsters-Forgotten-Realms
It's unlike any RPG supplement I've ever read before. There are no game mechanics, for any system, even though it's in theory for D&D4. What it has is lots and lots of information on various aspects of the Forgotten Realms, such as language, epithets, laws, jobs, trade goods, attitudes, entertainment, books and so on (even recipes for stirges!).
What it actually resembles the most, to me, is things like The Writer's Guide to Everyday Life in Renaissance England. It provides a wealth of background information for fleshing out a campaign.
