I’ve launched SupportHub !
This is a free WordPress plugin that hopes to help you manage support.
It will pull in Support TIckets from various networks ( email, twitter, envato, facebook, ucm ) and show them all in one place.
If it finds a similar question from the same person via different networks ( e.g. a tweet and an email ) then it will flag them as duplicate to help reduce time spent dealing with duplicate answers (or finding answers already sent via a different network).
