There's only one editor who approves stories, and that's Laurel.
It depends upon what exactly "weeks" means as to whether you should be concerned.
The approval span is sitting at a little over a week right now for everything due to the large number of submissions. Illustrated and Audio submissions are only approved on certain days. What those days are and how much time falls between them, I can't tell you, because I haven't been watching that closely enough.
I'd say that if you're just passing the 2-week barrier, you're probably within the current average of the overloaded queue for an audio/illustrated submission. If it's been longer than that and you're at or near the 3-week area, then you may want to use that link above to contact Laurel via PM
( Make sure your PM system is turned on in the User CP, linked in the forum header, and under "Edit Options" )
