When you log into bloghud.com and access your member profile (by clicking your name at the top of page) and go to add your external blogs, you will be asked for the url to your WordPress blog, when you select the WordPress type.
No need to add http:// when you enter the url. And please enter the full url to your WP blog, even if it is not in your webroot folder. eg: http://www.myhostedblog.com/myblog/
Please let me know by commenting on this post if you have any issues.
Once this is fixed up, it will be Movable Type for the HUD! yay!
