freia: Invitation email template for guest account, fguest[1-7], usage

Hi NAME,

Host freia is set up with IDL, and Spextool for both SpeX and iSHELL.
General instruction for using freia is located at
<http://irtfweb.ifa.hawaii.edu/research/freia/>.

Your guest account information on freia host is ....

  Username                    : fguest[N]
  Expiry Date *               : [3 months from account creation]
  Account and VNC Password ** : (will be mailed separately)
  SSH Address                 : fguest[N]@freia.ifa.hawaii.edu
  VNC Address                 : 127.0.0.1:590[N]

  * You are solely responsible to request account extension. Please
    send an email about 13 days in advance.

  ** On first login, above password would have expired and you would
     be asked to set a new password (see an example later) that is at
     least 16 characters long. Please have it ready before logging in.

VNC session
- It may not work without first updating the login password.

- Remember VNC will require an SSH Tunnel; see the instructions at
  <http://irtfweb.ifa.hawaii.edu/research/freia/#ssh-vnc>.

- Change of password for SSH login account does not cause change of
  VNC password. You are highly encouraged to change your VNC password
  via "vncpasswd" command.

- Changed VNC password will not take effect until the VNC server would
  have restarted. So let us know please when you would have changed
  the VNC password in order to start the server.
