A discussion can go unnoticed by other reviewers because there are no notices sent out to the reviewers attached to the discussion (there is an enhancement request to fix that). It would be good to have a date on the discussion to give the reader an idea if they are responding in a timely fashion.
I would love for the grant staff to get an email notification when there is a discussion. I also, would like the discussions saved in the request under activities or someplace useful to pull/reference in the event an audit is needed.
