Though the order of > messages listed in the references header might be used. I did a cursory test with Thunderbird (not the current version but a preview of version 3, so it might not apply to v2) and it seems to be basically the same as Evo. One thing I noticed is that when a parent is deleted the first descendant is promoted to be the new parent, even if other siblings exist, i.e. there's no representation of a "missing parent". The eldest son takes over as head of the family :-) This also applies to Evo. poc -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
