Abiword Word Processor

I installed Abiword recently. It seems like a nice app. I am playing around with it and trying to get used to it. It seems to have made it's self my default word processor. When I open emails with some documents or links in a page that require a word processor to view Abiword is the default. How do I change this? Even MS Word Documents open with Abiword now.

Never mind I figured it out.
