I'm an embarassingly noob user.
I got my gallery one-click to work, as well as Joomla.
I have to admit., I found the online guides & default guide/411 emails, VERY EXACT, and helpful. No problems here YAY.
My only gripe with DH, is that they don't offer a one-click HOME PAGE thingy. I REALLY NEEDED THAT. When I was with 1and1., they had that...but alas didn't have a wicked online gallery thingy to use
