Hello,
I answer you point by point to be clear

1. About import demo content, I’m not sure to understand you right. I understand that our pages not be deleted, but you say also that after importing the page, we will see the same settings, images, etc. as on your demo site. Our site is on production. I’m afraid that if after importing demo page ous shop shows the demo content and we don’t know how load our own content again speedely, it can make problems with search engines and indexation. I try to explain better. After importing the page we will have “duplicate pages” and we can choice which of them show on our web? Or not runs in this way. Have you somme tutorial about activate or desactivate demo content, to alternate demo content and real content speedely. Excuse my english, is difficult to me explain this doubt, sorry. (On thursday early morning I can try to do it because we have a complete backup on hosting and we can restore it if they are some problem. But I prefer know your answer before. If you can undestand me 🙂 )

2. About background color under the text of category names, don’t worry, I finded how to do thanks.

3. Aboutthe slider revolution, I supose if we do the point number 1 this question about the “Slide Revolution” will be solved also. I’m right?

Thanks a lot!
