+I like your suggestion because it's short and conscise. However, it would be nice to be able to refer to more or less arbitrary meta tags in links, not just "title". To do that, the link needs two parameters: the page name and the tag name, i.e. \[[pagename!metatag]]. Any sufficiently weird separater can be used instead of '!', of course. I like \[[pagename->metatag]], too, because it reminds me of accessing a data member of a structure (which is what referencing a meta tag is, really). --Peter
