This is not exactly oxygen related, I hope you don’t get angry.
If you are looking for a form plugin DO NOT BUY Piotnet form. Once you paid for the plugin you are on your own. The support is non-existent. They treat you like they made you a favour allowing you to buy their plugin.
Is reprehensible the company behaviour.
I’m not a ranting guy, I’m using Oxygen, Hydrogen, Oxyninja and Oxyultimate. You never saw me complaining. But the way Piotnet treated me, no way.
