I am contributing with some ideas during some time and I am not ranking in the community. Someone knows if the rules changed ? It is not easy to find this info.
Your ranking is shown on the right side of the Forum page, just below the top 10, in a large font. Very easy to see. In addition, each post shows your ranking (currently 116). Keep contributing and you'll move up.
Adding to what Curt said, if you go to your profile, you will see your current ranking and if you follow it's link you will have further info on: http://www.outsystems.com/community/leaderboard/
On that page you also see how the rankings score works.
Thank you guys
