Looks great! Thank you so much for writing this up.
I changed the 2082 (unsecure) links to port 2083 (secure) because it's silly to not use an ssl connection to cPanel to set up ssl on your website. Also, if you could add links to Johnny (johnny.heliohost.org:2083) for the people who aren't on Tommy. The instructions will be the same for either server. At the end you link to .htaccess instructions to redirect http:// connections to https:// You could just create a new page on the Heliohost wiki instead of sending people off to another site.

Railgun isn't installed. Check out http://www.helionet.org/index/topic/26914-ssh-on-tommy/?p=123429 to install free ssl/https on your site. Let us know if you have any questions.
There is no account in the system with that username, and neither of those domains are hosted on our servers either so I'm guessing you found http://www.heliohost.org/classic/support/scripts/delete to delete your own account already.
On this page https://tommy.heliohost.org:2083/frontend/paper_lantern/module_installers/main.html?lang=perl it says
Did you add either of those lines to your script?
