Newbie problems

[Kelemen Gábor]

Hi!

Just created the Hungarian Ubuntu translation team, but i have some 
problems.
I tried to ask  mailman-admin lists ubuntu com  to create a mailing list 
for us, but the mail bouced with the following:

A message that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following address(es) failed:

  mailman-admin at lists.ubuntu.com
    local delivery failed

So what's the correct way to create such a list?

Other problem is with Rosetta: when i login and try to translate something, it says, i'm not an  official translator for this package, and "No translators currently designated for this PO file." Besides that, i'm unable to upload translations, due to permission problems. 
How can i be (or make somebody else) an official translator? 

Thanks in advance.
