unsubscribe?

[Murilo Lacerda Yoshida]

  Hi all,
  I tried to unsubscribe me from the list in the 
http://lists.umn.edu/archives/mapserver-announce.html link, but it 
didn't work ... Probably because I didn't join the list by this link ..
  How do I unsubscribe me?
  Thank you guys for all the support you've gave me during this time ... 
I'd like to say that this is probably the best list for support that 
I've found on the net ...
  Thanks again,
    Murilo
