If you're talking about the "Current Points" that happen when you hover over your name on the forums here, they accrue as you complete "badges" -- not per post. Otherwise I'd have well more than 470 ;-)
Thanks for bringing this to our attention. We're working on the points system for the site on the back end so my apologies if they aren't racking up for you right now. I'll bring up your particular case with the rest of the team, but we're continuing on improving the experience you have using the forum. Thanks again!
