  * Slack will be the main communication channel.
  * Navigate to https://seis664.slack.com/[https://seis664.slack.com/].
  ** Click "create an account" and remember your password. You should use your St. Thomas email. Whether you use it or another email, you will need a SEPARATE and DISTINCT password from any other Slack accounts you have. This is just how Slack works; you have to maintain multiple accounts.
  ** Confirm you can read messages. Try posting to the https://seis664.slack.com/messages/general/[#general] thread.
  ** The channels are not cleared from the previous semester. Have a look, you'll get a feel for the class. SEIS660 & SEIS664 alumni may lurk and assist if they feel like it, as long as they are constructive.
