We are even less tax experts but we see that is possible on other websites/services provider but for Envato is not possible or they just not care. Also, for me is unreal that the Envato (company who is made millions per month) has only 1 person (Ben) who is a “bridge” between us here on the forum and the rest of the company.
There are moderators who are reading all this but the real “connection” to Envato team is just 1 person and chance that someone actually see what the authors are talking/are complaining about is very low.
