Re: Re-submit friend request
You pose a good question. It would be useful to have the ability to re-request friendship, or at least nudge a given person to reconsider.
Of course, as you suggest, there may be other issues like the original email was overlooked or filtered out as spam and never seen. In this case, there’s not much that can been done, especially if a member does not check their profile on a regular basis.
But having a feature to re-request action or an admin-configurable setting that will auto-remind members every week or month to visit their profile would be a nice addition to the platform.
I suggest creating a new enhancement ticket in trac.
