To my knowledge, there's no way to track how many posts you've made on the forum besides rereading all your old posts and counting them manually, so what about a number counter of forum posts available on your dashboard when you go to check all your other stats?
If you add the Extra Userinfo section to your profile, you can see your total number of posts as well as get a link to your recent posts.
That aside, I wouldn't mind adding this to the site dashboard either. Possibly add a separate page if it gets too cluttered. Some place that lists account info already shown on the dashboard and new stuff like your posts, total number of achievements, forum groups you're in and the likes. Have it in one place for easy access.
I don't really see the need for this. If you have the main user info widget on your dashboard (the one with your sP, CSC, etc) you already have this info on the dashboard. Just hover over your user name.
Too much info displayed can be as bad as not enough info because the useful stuff gets drowned out by the overload of info you aren't actually looking for all the time.
