This FAQ and its title assume that the link is going to be in an entry, or possibly the profile. I propose to either change the title to "How do I add a link to another journal or website in an entry?" and create a separate FAQ and titling it "How do I add a link to another journal or website on my profile or in my style?" also covering plain HTML links and linking to the howto on LJ-specific links and pointing out the places that one may enter these (or pointing back to 67 for HTML and LJ-specific links), and the links list -- or else covering all the places that one can link in FAQ 67.
(Looking at it laid out like that, I think I prefer reworking 67 to apply to most all instances of linking.)
