Simply create a page with "User:youruser/Sandbox". Your user... is your username (LivesByProxy). Sandbox can be replaced with any name; as long as it's not something random such as "QWEfqlwkenfdsapdmf" or is against the wiki policies (profanity as an example), it can be "Sandbox for My Poor Self" or "This is my Sandbox so no touching".

As for your profile, do I simply just copy-pasta the "About Me" and below part (of course without "Could you copy-paste...")?
