Hi,
Can't find an uploader for Mac, only ”content_uploader.exe” and that's for PC I guess. 
So how can I upload content if I use a Mac?

Yeah I had the same problem for a year since I started, people from the groups liked my characters and wanted to buy them and I would love to be part of the market as I think I could contribute well, but after 5 years of asking I gave up, they will never make one and I'm not gonna buy a new computer that I do not even know how it works because they can be considered enough to include all their users, they will tell you  "is on the way" but they told me that every year from the past 5 years, so is pretty much a big NO
