When welcoming a new admin, there are a bunch of things that should be done. This post acts as a checklist to make sure that nothing is forgotten 
-
Tour of the Freeside room
-
Tour of the servers & desktop infrastructure
-
Securely exchange the root password (and the old one too, just in case)
-
Grant the Admins role on Discord
-
Add them as an admin to the Facebook page
-
Grant admin privileges on the forums
Don’t forget to edit this post to keep it up to date and add things that are missing.
