First, welcome aboard. I can’t believe LP pulled such a dumb business move. Advertising revenue will never pay off long-term as well as satisfied customers.
Second, these forums are basically customer to customer. While a “honcho” may pop in once in a while, posting here is not a good way of contacting Dreamhost. This is, however, a great resource for basic (and advanced) assistance in solving problems and maintaining your site(s).
I suggest sending your follow up question to sales directly. Unfortunately, I do not know the answer to your actual question. Maybe you will get lucky, and one of the “honchos” will see your post and answer here, it is a good question.
On edit: No phone contacts are available. I have not missed this “feature” in my dealings with DH.
