_me

If the current user is a Person in the current Space, return that Person -- Function

_me (warnIfNotLocal) -> Thing Type

warnIfNotLocal (optional): Iff true, give a warning if this isn't a local Person. Iff false, produce Empty
Produces: The Person who created the Thing, if known. This may be empty.

_me is the usual way to customize a Space based on who is looking at it. If the page is being viewed by a logged-in User, and they are a Member of this Space, it produces their Person record.

If the viewer isn't logged in, or isn't a Member, this will produce a Warning. If you don't want a Warning (for example, if you want to be able to do something else if this isn't a local Person), say it as:

_me(warnIfNotLocal = false)

NOTE: the high concept of _me is important, and will be continuing, but the details are likely to evolve a great deal, to make it more usable. So don't get too invested in the current behaviour.
