Support is slow or dead

Could be good plugin but for simple answer have to wait a year also this plugin left a garbage in SQL like some admin anspress users WTF???. When I asked author how to delete those admin users i get no answer from last year !! Maybe this is kind of backdoor ?! .
Anyway you can use this plugin on your own RISK .
Better choice is to get sabaia disciuss for 25$ and everything works like should be.
