x namespace

All new accounts automatically start in the .x namespace where anything goes, and since it's just a play space - intended entirely for xperiment & xperience - nobody gets hurt. 

You can play here with a fictitious id or your real one, it doesn't much matter.  Once you have registered your profile, you can create trading accounts in the x namespace and create other namespaces within it to play your own games.

When you want to play for real, you will need an authenticated id in an existing namespace.
