Changes

* Change the website committee to the communications committee with a web and email subcommittees. The email subcommittee should be responsible for communicating with various committees that need announcements to go out at various times. Ideally the first year would create a script for which messages to send when, and who to consult with. e.g. (Call for keynote, Keynote voting opens, Keynote voting final reminder, Call for submissions, Call for submissions reminder, Submission voting, Before you come to the conference, Welcome to the conference, Post conference survey, etc.)
