Wow! I am totally confused now. I've tried several times to post a new hub, but when I get to the place where I choose a format, I get an error saying, "Please fix these errors before continuing: Please specify a web address for your Hub." There's a "perma-link", but it's grayed out, so I don't know what to do. I've never seen that before, and I have no idea what they are wanting. Any suggestions?
