Hello everyone!

We're proud to announce our new badge system, allowing you to highlight your achievements on the site, as well as your service in the armed forces. There will be more to come soon, so stay tuned!

Badges can be found here (at the bottom of your User CP lefthand menu): https://www.pprune.org/badges.php?do=viewbadges

If you do not see them, try refreshing your page. Post in the technical help forum if you have any other issues.
