Thank you very much for this info. Based on what you wrote ("I'm afraid that they [Apprpvals Team] are only in the office part time on the weekends"), I think it is quite misleading what is written on Dreamhost website:
"Sales & Support, at Your Service.
24/7 in-house support, here when you need us."
Knowing that there is 24/7 in-house support is one of the reasons why I signed up. They should probably update the website, adding something like "We offer 24/7 forum support, but approvals team works only part-time on weekends". This would be more honest.
