[Greg Grossmeier]

20:43 < mutante> .join foo
20:43 >>> topic changed by gregpush: mutante
20:43 < gregpush> mutante : You're up
20:44 <@ greg-g> huh
20:44 <@ greg-g> watch this
20:44 <@ greg-g> .join something
20:44 >>> topic changed by gregpush: mutante | greg-g
20:44 < gregpush> Sorry, I don't understand the current topic
20:44 < gregpush> I won't accept new commands until the topic is fixed.
20:44 <@ greg-g> my - confuses it
