A Cup of Joy's dashboard

I've installed the widgetbox from the widget network channel Food. But, when I click on the button to say I have installed it, I keep getting a message about how the blog url is not linked to the feed. What?! I don't understand. How do I fix this? My overall impression of this new network is not very good. There are a lot of kinks that need to be worked out before going public with this. Oh, too late! It already has gone public. Congratulations on creating something very frustrating and confusing. Now....go forth and fix so we can all enjoy this idea. I do believe it is an excellent one. It just needs some fine tuning.

I'd like to sign up for a network. When browsing them, I selected a channel, went to the next step and decided it wasn't the right channel for me. Now, it won't let me change it without first installing the channel I do not want to be a part of....Help!
