nope not at all. the one thing they don't have tho (as far as I know) is a way to skip the free trial on hosting.
the 9.95 gets deducted when go from free trial to paid account.
Dreamhost can't offer free trials on domain registrations. If you register a domain you own it for that year. You can choose to have your hosting here or point it elsewhere.
If you want to reverse it (not reccomended if you actually want that name) then contact support quickly, they apparently have some latitude to reverse brand new domain registrations, but that won't last.
