I just wanted to give a big thanks and shout out to Jerome Mingo who is the modzzz developer and creator of several popular plugins for UNA. Let me explain. I've purchased most of his plugins for my site https://flapchat.io I uncovered several errors and nonfunctional scripts that were perhaps unique to my installation.
Over a few days, Jerome personally worked on my site to ensure his plugins work properly. He spent several hours debugging and troubleshooting code. He installed code on my system and tested it personally. I'm not saying this is what he will do for everyone, I'm saying this is what he did in response to my original petitions for help. This guy obviously stands behind his products and I can wholeheartedly recommend them for your site too.
