[Rivet] Trac login changed

[David Grellscheid]

Hi all,

Just to let you know that the trac login for YODA and Rivet has changed 
to use the SSH password if you are a member of the rivet/yoda group. To 
determine which groups you belong to, run 'groups' on login.hepforge.org

For non-members, the login will remain the same. In the near future, 
Trac account management will be enabled, so that bug reporters can 
self-register.

See you,

   David
