Technical Question

I've gotten in discussions about books a few times now, either in comments or PMs. Is there a way to embed links to Amazon in our messages so this site gets their affiliate credit? I see the ad in the corner of the site that lets the site get a commission from Amazon shopping, but don't know if we can make that more general.

Just wanted to know in case we can make those links ourselves. Might as well - I'd be quite happy to see the site get some credit when I shop there.

Thanks for any help.
