I'm wondering if there's any way to add custom fields to a blog entry. At the bottom of every blog entry I'd like to add a field for the site link, a link to a site review, and perhaps a link for a free gallery. I know that I can just create these in the entry itself, but it'd be nice if I could have custom fields that I could plunk the URLs into and have the software do the rest.

Anyone know if it's possible to do such a thing with Wordpress.

Thanks
Michael
