Anonymous Checkout, Developer commit

[Peter Reinhardt]

Hi,
I am currently working on a project at sourceforge.net.
I checked out using the pserver anonymous login. Now I have changed some 
files and I want to commit my settings, but I am not able to do this, 
because the anonymous-user does not have writing rights.
I then tried to login via ssh with my username at cvs.sourceforge.net to 
authorize my commit process, but the server answered with
----------------------------------
Welcome to cvs1.sourceforge.net

This is a restricted Shell Account
You cannot execute anything here.

Connection to cvs.sourceforge.net closed.
----------------------------------
Now how I am able to commit my changes to the repository?

best regards,

Peter
