[Mailman-Developers] Using Mailman scripts from cgi

I'm probably going in the wrong direction, but I'm trying to create my own page for subscribers on an Ubuntu server.

Before I get my cgi form working, I'm trying to use the command line script "add_members" and can't get the right syntax for using stdin. I've tried:

$ ./add_member -r - listname joe@test.org

and

$ ./add_member -r - listname < joe@test.org

but neither works. I just get the command's help output.

I am in the bin dir with the script and I'm a member of the list group.

What am I doing wrong?

Thanks,

-Tom
