heres my idea :
Shut down the main gameserver on one day in the week (lets say Monday) for 2 hours, and invite all players to the test server.Re activate the red chat we had at pre release on the test server ,for better communication.
Use the testers as rat labs /slaves or whatever you see fit.
After that ,give everyone who did succsessfully participate a little something as reward on the main server.
The idea is to help the devs , who are obviously having a shit ton on their plate , test the stuff they are working on under real time load and player expirience and giving us (the community) a glimpse on what they(devs) are up to all the time.
sidenote:normaly i wouldnt suggest any rewards , but if it helps to attract ppl wth
