I've removed domain mapping from early adopter accounts. This is a paid only and permanent account feature. I don't actually think it works yet but when it does it'll require a paid or permanent account.

Accounts can now be accessed by a virtual domain, ie. http://yourusername.scribbld.net. Pretty nifty! This is availble to paid and permenent accounts right now!

Paid and permanent accounts also have access to their full rss feeds.
