Please remember to update your PWS, especially today (and early if possible) as the update may take a long time for some people.
Also, an experimental Arma3Sync repo has been setup, if you want to try it out: http://srv1.zulu-alpha.co.za/repo/main(2)/.a3s/autoconfig
You can get Arma3Sync and read it’s documentation here: http://www.sonsofexiled.fr/wiki/index.php/ArmA3Sync_Wiki_English
