I have a Case system in place for handling "Salesforce and Other Requests" in our company. People submit Cases, they get handled and closed.
For both "fairness" purposes (a Case is meant for something that takes "at least 15 minutes" by the definition we've all agreed upon), a Case is not created when we're doing a quick-and-dirty request (making a record change that is locked out to most users, checking a log from one of our GotoWebinar processors, etc). So, we've adopted people chattering on the record in question saying "please do whatever". We then comment back (eventually) the word "Done" at the beginning of the final comment (might add extra comments, but always prefixed with the word "Done").
Either using Hashtags, or continuing with the simple prefix-word "Done" system, we'd like a report to show all related Comments (either "starts with 'Done'" or occurrences of a hashtag, perhaps #SFAdminDone as an example). This way if anyone questions the SF Administration is sitting around doing nothing, we have not only our chatter feed "per user" (verbose and overkill and not simplified), but better a Report (to accompany Open and Closed Case Reports).
I've checked (quite thoroughly I believe) the SF Help site. Best info was two items, one a post from @Bob_Buzzard, and the other, vague mention that Feeds and Comments are available under the User object specifically. No help there or the 15-20 other pages I read through.
Help? Any thoughts?
The alternative is to create and close a Case for every "micro request". Not appealing - time consuming when it was a simple item that took 1-10 minutes usually.
