Remember, improving Ubuntu from within is something that LoCo Teams can and should be participating in. We love Ubuntu, lets make it better. Squash bugs, improve documentation, work with developers, become part of MOTU, improve and support existing user groups and special interest groups. There are dozens of ways we can contribute, none of which require money or legal guidance.
