Small but very useful addon. In our community we have a classifieds forum where threads need to go thru approval (checking that a price was given, pictures attached aso.)
OOTB the mods could only delete, but no info could be given back to the user directly. (one needed to start a conversation, explain reasons ...)
Now this is all in one place and the poster gets an alert if deleted (and also if approved).
Had a little bug initially (alert for delete did not work) but response here within minutes and also the fix !
