I have couple of subdomains that I want to link to with page tabs. (E.g. a photo gallery.) I can not figure out how to set that link up. For example, when I create a page called calendar it creates http://www.domain.org/calendar. I want that link to be subdomain.mydomain.org/calendar.htm. Is there a way to do this?
If you want your navigation to say something like Forum, then when you click on that, it takes you to your forum URL, then grab the Redirectify plugin, create the Page called Forum, save that page. Then edit that page and add a Custom Field with a Key of 'redirect' and a Value of the url of your forum software.
