User Achievements is member activity system here at EFX it lets you track how active you are and rewards you with 'kudos' when you reach certain goals.
I recently updated it to reflect some new items and changed the layout some so it is easier to read and overall just to make it look nicer.
You can find it on your profile by clicking your name (or someone else's) anywhere in the forums, that will take you to the 'View Profile' page.
Once you are there, scroll down to the 'Achievements' section to view this summary.
