I am currently running WP-o-Matic and it only pulls in a snippet of the text how do I get it to pull the whole text from the original source or is their a better plugin to do this?
Most people have their feeds set for excerpts only for just that reason....to keep auto blogs from doing that.
You can't program it to pull what is not there...it is set from the source to only allow an excerpt. Instead of coming up with a way to totally scrape content from someone else's site (because that would be blatant infringement) , why don't you use something like Caffeinated Content, or pay for a service that provides you with content?
