Hi All, semi-copyright noob here and I couldn't find anything through search.
I want to design (I have a mock up already) a theme for a specific use and sell it as a premium theme. Do I have to build the html from scratch and convert? Or is it possible to "highjack" a current open source theme, make my significant alterations, and then sell it?
Which leads to one final question, how can you determine which free themes on wordpress' theme search are open source vs. free by privately copyrighted?
