There used to be an "create an idea" link in the upper right when you're browsing these threads. It appears it's gone. : /
Other than that, you might have a chance at one of the staff taking a look at a thread and passing the info along. I would mark the thread's header with a [SUGGESTION] tag.
How would one edit the thread header?
I believe you have a limited time to edit a post once it's posted but I can't remember how long offhand.
It wouldn't hurt to post a new post anyhoo; this forum isn't quite as busy as, say, Photoshop's forum.
