This plugin is completely useless.
The only one that can add tickets is the ADMIN.
I created an account just to downvote this plugin because it wasted 30 minutes of my lifetime, making me believe it actually can do anything.
D.O. N.O.T. D.O.W.N.L.O.A.D.! Trust me.
If you buy it, then it may be useful, however there is no way to tell because the authors aren't smart enough to let anyone actually test ANY functionality.
Whoever upvoted this plugin to 4 stars obviously got paid to do so or was a part of the scam.. err... development team.
Stay away from this. Download something from people that deserve your support.
