I've tried a bunch of different ways of formatting the cancel/confirm links in the notification emails, but the only way I've gotten the links to actually work is to leave it as a plain link (using the #link_cancel# tag, for instance).  But when I do that, the link looks ugly in the email, showing the entire URL. I've tried editing the source code of the emails and adding <a href="#link_cancel#">Cancel Reservation</a> but those links don't work. Any suggestions?
