We had another example of that unpleasant, but perfectly legitimate behaviour when mt2k erased most of his nodes (GoodBye :-)). In that case tye restored all nodes from backups (Re: GoodBye :-)), can't we do the same?
I think that we cannot rely on thepen mirror site, we should have a local copy of root nodes, probably after they are approved, just in case we need the original node. I think we should not deny our past experiences, after all they made us what we are now.
P.S.: chunlou must have his reasons for behaving that way, but I would like to know those reasons.
