There is a line that reads:

Copyright (C) 2008-2010 python-messaging developers

Typically, you would use that format for a formal legal entity, such as a company or some other group that has legal status.

I recommend you update that line to individually name the developers who have contributed code.

Thanks.

It's fine as it as IMO.
