I'm in the process of migrating my wordpress.com blog to be hosted on Dreamhost, but I've screwed things up.
I'd like to wipe my space clean and start over, but don't know how.
What steps need to be taken to reset my account?
Your best bet would be to delete your FTP user data and create a new one. Start clean and give it another go!
If you need extra help or have questions, feel free to contact our support DreamTeam and we'll help you figure it out: http://bit.ly/PfpbbY
The other way would be to log in via FTP, delete the files and then remove your database.
If you're importing from wordpress.com I'd suggest using our one-click installer, and then using the built in WP export/import tools
