change "checkout our new themes" to "check out our new themes" — checkout is a noun, check out (space between those words) is the verb.
other than that: congrats!
This has been fixed.
you can't actually change the new theme colour (unless that's only me) but I have tried to alter it from any of the classic or currently 2.0 colour and it is stuck on blue :( there go my dreams of pink
