Examples for {thing}++ could be clearier.

[Jamus Jegier]

Spent a while trying various forms of {thing}++, {Thing}++, and {THING}++ trying to get karma to work, when I actually needed to simply use thing++.

It would be clearer if the help said:

{thing}++ add 1 karma to {thing}

Or simply

thing++ add 1 karma to thing

Good point. I'll try your first suggestion next time I have a chance to update it.
