I am following Wrox Book Sharepoint 2010 Professional Development.
In chapter 9 (Electronic forms) they told me to create a training list with some columns - done.
On chapter 12 (Workflows), they told me to create a content type with the same columns, and then associate the list with the new content type.
So, whats the deal here? whats a content type? What happens when I associate a list with a content type? what happens if I dont associate them?
The item content type was already there, can I delete it and leave only training content type?
What else can I do with content types?
