How do you get punching power?

[Douglas]

If this has been asked somewhere else then I must have missed it..

I get the rep system now, and that punching power relates to how many rep points you give or take away from another person when you 'cc/sc' them, but how does one build up their punching power?

I think so I asked it in the 1,000 posts forum

Tis a mystery ain't it
