I'm thinking about buying a theme from wpnow for wordpress and I'm noticing it has 4 options: 1. Branded-single use 2. Unbranded - single use 3. Branded - multi uses 4. Unbranded - multi uses for the single/multi uses, what happens if I want to change domains once I install the theme, will buying the single use not allow me to do this? what's the difference between branded and unbranded? It seems like on the page it says branded means there will be links that go back to wpnow.com in the footer that can't be removed so I'm not sure what this means.
