wherevis

Syntax: wherevis

Toggles your visibility status on the ‘where’ list. This command cycles
through three different states:

1. Visible: You appear normally on the where list with your full name.
2.
Anonymous: You appear on the where list but your identity is hidden.
3.
Invisible: You do not appear on the where list at all.

Each time you use the command, it moves to the next state in the cycle. The
command provides feedback about your current visibility status after each
toggle.
