let's use this for communicating among SW team

[Armando Fox]

hey folks -
so as not to bombard marti, bjoern, and the other moocchat folks who are away for summer with code-related emails--
let's use github issues to communicate among ourselves from now on.

• for just chatting, where we don't need a permanent record of the conversation, use skype or other IM
• for an ongoing discussion about a design issue, bug, etc, open a new github issue.

thanks for your cooperation
