It would be great in doing this if a count of un-actioned requests was maintained somewhere, possibly by type as well as total.
Applications for this (in addition to the site itself of course!) could include:
Chrome Extension button showing badge with number of requests awaiting action
Ditto mobile native app
Ditto mobile web app (i.e. website designed to be bookmarked to iPhone homescreen with an app icon)
Ditto Microsoft IE Pinned sites
Ditto Growler on Macs
And I'm sure others I'm not aware of, e.g. the equivalent in Firefox etc.
All of these could access the count(s) in various ways provided it could be output somewhere (even if that means a very simple page containing only the number itself).
