Since there isn't a formal feedback system, I just decided to create a post in one of the Beginner or above forums mentioning the user in the title and giving a brief statement of the who, what, and why, but without using any personal information -- any more than their forum username.
Not completely! I still have all the iTrader data and it will be imported into the new feedback system once we start overhauling all the forum's additional addons/features/RDFGS 2.0 stuff, coming up. This big forum overhaul/whatever you want to call it has been planned for a while and is what essentially is coming after I finish up with he VPN launch, as far as the order of things goes.
There are a few addons that handle feedback in the similar way iTrader does.
