What is the best way to move a form created in Adobe to Acrobat.com?
I assume when you say Acrobat.com you mean Adobe FormsCentral (formscentral.adobe.com). If so, there currently isn't anyway to import a PDF form in to FormsCentral. you would have to recreate it within FormsCentral
We just recently added support for importing an existing fillable PDF form.
