This is for me to sort out my tag issues. Some of my tags eg "due south rec-age" aren't working because of the ickle spaces, it's been driving me nuts, here is the interim solution from http://www.livejournal.com/support/
Tags containing spaces will erroneously display a "Sorry, one or more specified tags do not exist." error message when clicked on. Until this issue is resolved, you may access the tagged entries by replacing the '+' character in the tag with '%20' in your browser's URL bar.
