Hello,

Hans, have you been Cc'ing the list?  Currently I see
(both via my personal mailbox and the archived mailing list)
five messages from Phillip with this subject, and none from you:

    http://news.gmane.org/gmane.comp.gnu.parted.devel

If mine makes it, it will be the sixth.

It is odd to find only Phillip's posts, and to learn of your
replies only via the parts of your messages that he quotes.

Due to the way parted-devel (via mailman) has mangled some patch
posts by me, I've resolved to use only bug-parted at gnu.org from now on.
