When you use /origin, theres no way to find out what origin someone is without going through every origin with /origin get.

There should be an argument in the same column as get/set, which could be check.

It returns the id of their origin, so par example, bObpLayz is phantom, and when you run tye command /origin check bObpLayz, it returns origins:phantom.

Could be useful for server admins when they want to check a playera origin to make sure they're not cheating, and what theyre doing is an origin power.

Added in 0.7.2 which was just released. :)
Use it for example like this: /origin get Apace origins:origin
(The last parameter is the layer, e.g. origins:origin for the default layer, or for example origins-classes:class if you want to check the class from the Classes add-on)
