Hi there $USERS_REAL_NAME,

Welcome to yoyo. Your request to create an account has been successful.  Here are some details:

Login: yoyo.its.monash.edu.au
Username: $USERNAME
Password: as you provided on the form

Please remember to change your password (as you will be prompted to) upon the first login to yoyo.

It is recommended that you use an SSH client to login to yoyo, as telnet is not as secure - clients are available freely on the Internet, for all different operating systems.

We hope you have fun using yoyo. And if you have any problems, please do not hesitate to contact the Accounts group (accounts\@yoyo.its.monash.edu.au) or even me ($EMAIL_CREATOR), and we'll get back to you as soon as possible.

Have fun! 

Regards,
$CREATOR_NAME.
