I did the one click install, created a second FTP user, but can't seem to get out of the /home/seconduser directory into the wordpress root. Not sure what the navigation should be like.
You should have had access with your normal user account. See http://wiki.dreamhost.com/FTP#Locating_the_Correct_FTP_User for how to figure out which user ID to use.
Remember, we have a one user per domain policy: http://wiki.dreamhost.com/One_User_Per_Domain_Policy
Thanks I was using a secondary user account. Switching to the main one worked
