Hiya,

What do you call it when you can for example: add {userID} inside a PM, and the person's name automatically gets added upon sending?

What do you call the {UserID}? - Is it a name space?

[logic_earth]

{UserID} === UserID surrounded by curly braces?

String replacement, maybe.

[{RainmakeR}]

I would call that a 'token'.

[kyberfabrikken]

Maybe a macro or a placeholder?

[Kailash Badu]

slots

[wysiwyg]

I'd also go with placeholder.

[Stormrider]

placeholder, or even tag - although that could be confused with HTML tags obviously.

[Czaries]

I generally call them tags or placeholders, tags more frequently.

[cuberoot]

I'd call it a variable.

[AnthonySterling]

After much deliberating, I'm going with Token.
