I do wish there was a way to search for posts by the level of the poster. If there is already a way to do this, I couldn't find it. But it seems to me that the amount of irrelevant and off-topic posting is on the rise, and it's becoming more of a chore than it was before (and it always was a chore) to sort through and find the posts I care to read. So what do you say to adding this feature, so we can just search for all posts by "staff"?
You can search for specific authors. Are you looking for just a 'search by moderator' ?
My guess is that slipshod is looking for something more like a "dev tracker" that some sites have. In this case, it would be an "imm tracker" where all the posts made by imms would be highlighted in their own section, most recent first.
