TECFAMOO is first of all a MOO for research and for researchers. Since it is constantly modified and since our resources are scarce expect to stumble upon bugs sometimes. We would be very glad if you could report them to us. Ideally you should use the bug reporting form:
Usage: @bug-report <bug report title>
@bug-report @go is broken
this form will ask you a few question and optionnally will allow you to automatically include your last error traceback. So use this form as soon as you get a traceback please. Thanx!
