I realize this may be an extremely basic question, but I'm confused about the legal issues that come with starting a blog and using a theme. I want to use the Clean Blog theme (by BlackrockDigital). This has an MIT license in the repository and a copyright logo on the bottom of the live demo.
If I use this theme, do I have to keep his license or make my own? Can I put my own copyright logo on the bottom, because technically my content is original although the theme isn't? (It's a blog, after all.) Or am I supposed to use their copyright? Lastly, I know an MIT license means that this should be "free of charge" -- does that include ads on a page?
