I am writing this not to be unkind, but to forewarn people of the potential issues.
First off, the people that built DMS have done a herculean job. The concept is so amazing and I know it will work to standards very soon. The staff has been very quick to help with customizing and I am so appreciative of that.
The challenge is that DMS is very buggy and even more difficult than Pagelines. I learned a lot figuring out workarounds so that is a good thing.
DMS was billed as a designer dream, but the learning curve is like Flash or Dreamweaver and you need to know how to do way too much custom coding in an environment with gobs of nesting. I just don't do well with that, no matter how hard I try. (The customizing is three times as complicated in DMS.)
I have used pagelines for 2 years and I LOVE it. I decided to teach myself DMS. After two weeks I have completely given up and am starting over in Pagelines. This means I will be up all night re-building a DMS site that just doesn't function, in tried and true Pagelines.
DMS is so difficult and so buggy. I am remaining calm because this is not life and death. I am fortunate because the two weeks loss in income is minimized by a second wage earner in my family. Not everyone has the luxury.
I know I will return to DMS someday, but for now, Pagelines Framework is true blue and I encourage you to stick with it.
