Rick, I think you're off to a good start. If you don't mind my being slightly presumptuous, here's how I might begin the article:
UR Comments is a WME plugin tool to streamline the process of responding to Update Requests from users. It can autofill the comment box, based on UR type, or you can manually choose from a curated list of responses, depending on your preference.
If you have UR Overview installed, UR Comments can integrate with it to provide reminders at 4 days and 7 days, for efficient clearing of URs.
... something like that. Then go to your detailed tab descriptions.
