[development] Overriding taxonomy term page

Hi all, I'm wanting to add a link to the bottom of a taxonomy term page, similar to the feed icon that is already there. What would be the best way to do this: add a hook in to the taxonomy module allowing other modules to insert their own bits, send the page through a theming function, or some other method? Any advice appreciated. Thanks, Dan -- Dan Karran dan@karran.net www.dankarran.com
