Search for GM posts/special thread icons

Currently, Advanced Search has the Dev Tracker checkbox to search for posts made by developers and/or community managers.

It would be nice if there were a way to search for posts made by GMs and/or other staff as well. There have been some recent posts by Enkrateia that explain game policies very well, but GM posts don't get the crown, and they don't show up in Dev Tracker searches. It's some very useful information that's effectively hidden unless you know it's there, and being able to at least search for it would help a little with that.

Giving those threads their own special icons, too, would be even better. Or at least give other staff an option to icon-ize threads they post in. Some posts really don't merit wider attention ("Hey so and so we've rectified your account"), but some of them do.
