Well worth a try.
Basically put, had problems with my past hosting, dropped by dreamhost, noticed there was a 10th anniversary special, I signed up... then I tell my co-worker, he signs up, then I tell my employer he signs up then moves all the domains on our dedicated server over (which included some that I had).
So my account is older than the account that the domain would be moved from. But both accounts used the exact same promotion. Also the domains on both accounts were already in existence just had their nameservers changed so wasn't obtained with anything dreamhost related.
I'm wondering if I went ahead and pre-paid the bill for next year (ie: the 10th anniversary was first year free then something like 110.10 per year after) that might take it out of the "promo" status.
