Condition on Templates?

[Dorign]

My forum uses set templates (don't like to allow users to change templates), however, a few different boards have different skins. I was wondering, however, if there was a way to do this on "non-forums." For example, I've recently installed the arcade. However, there is no where for me to choose which skin is being used for the arcade.

Is there some sort of "if conditional" string to perhaps change templates on different sections of the forum?

Thanks!
