I need to have mentioning people possible in the LIST COMMENTS area - I'm really surprised this doesn't work in this area presently, also because it shows up there to be a possibility but then doesn't function (which is really confusing for guests).

I intend on using this area for clients to submit retainer requests by mentioning me in a comment in this area (so that I get a notification directly). I would REALLY appreciate if you guys could get this working. It makes things very straightforward for my clients to be able to have one quick place to submit a request and upload files without having to TOUCH a single task below (but view - for a good overview for their knowledge).

Same goes for being notified of any files uploaded to that area. It would be great to get notification of that.
