I have been running around on Google for days trying to find out what premium themes are available here on Postach.io. I think I finally found the answer. Seems that the themes for the free account are the same ones for the premium but you can customize them with a premium account. I wish there were more themes. I change themes a lot. Hopefully they’ll add more in the future. If so, I will seriously think of upgrading to a paid account. ^_^
