Thanks for posting that support ticket response, daisygirl.
That figby.com link was very helpful. The blog entry at figby.com has a link to a blog entry at Randon Bytes:
that gives a fairly detailed account of context and motivation for the new policy (NetSol, anyone?).
Good to know the support ticket system is working. But since this forum is another means of providing support, and since this issue is of some general interest rather than an individual problem, I'm still wondering why there has been no response from a DreamHost rep to my initial post. Something like daisygirl's support ticket response would have been fine as an initial DreamHost response here, and might have even prevented some support tickets from being generated by worried DreamHost customers.
Also, the question is still left open of whether a lock status option might be a good feature to have.
