One of the requirements to become a Ubuntu member is to have signed the Code of Conduct. It may seem like a formidable task and it was for me. I was only able to accomplish the task on my third attempt. There are several web sites that purport to make the task easier. Two are from Ask Ubuntu. "How do I sign the Ubuntu Code of Conduct" http://askubuntu.com/questions/100275/how-do-i-sign-the-ubuntu-code-of-c... and "How do I make a PGP key?" http://askubuntu.com/questions/100281/how-do-i-make-a-pgp-key There is also the "Code of Conduct Signing Assistant" on Launchpad itself. https://launchpad.net/code-of-conduct-signing-assistant. These sites, especially the last one, should make the task relatively easy.
