Q1. You need to agree to the changes I requested in the comps before I sign the Modification Agreement. I do not want the changes YOU propose or "Rhythm's recommended changes". I need the changes I proposed in my original response.
Q2. Who is NopCommerce? Does my CMS go away if they go belly up?
Q29. Probably OK. Can I change the column title from within the database? If I'm able to do batch uploads, this should be possible.
