Is there a way that I could set up a "Reminder" option that can be initiated by users on my site to "Remind" another user to access the site again?
UserA goes to UserB's profile and clicks on the option "Come back" to initiate an email to UserB's email address from the site. UserB's email address is not disclosed to UserA.
A simple button that, once clicked, will send one single email from the site to the user that says something like "I miss seeing you...please come back!" The body would include the user's username and an invitation to come back to the site to update their profile, and let them know that someone on the site really wants to connect with them.
I think this would be beneficial and give more "power" to users to reach out to inactive accounts and gently remind inactive users that the site still exists.
