So I received an email that I had more than 300 images accepted this year, so I was given a free 12-month membership to Creative Cloud Photography. That is very nice, but I am on Linux/Ubuntu and have been using the Gimp for my images for many years. I was going to download Photoshop to see if I can get it to work with Wine, but the download page does not let me download it and gives me a "not compatible" message. Is anybody using Adobe apps on Linux?

I did try it years ago but only with Photoshop Elements.  It was OK but I couldn't get everything to work.  If you're happy using the Gimp, I would stick with that.  Windows drives me to the point of insanity, or possibly beyond it
