EVE Online's next expansion Apocrypha plans to bring new and exciting features to the universe, but CCP needs your help. Tonight begins the fleet testing so pivotal in major battles and it will be in full swing on the Test server:

The launch for EVE Online: Apocrypha is rapidly approaching! It will bring an immense amount of new content, tweaks, and optimizations to EVE; these will all affect how stable, smooth, and fun fleet fights are. We think you'll be happy with the changes we've made; of course now we need to put it to the test in a "live-like" situation! To that end we will be running a series of fleet fights on our main test server, Singularity, starting today and we need your help to do it.

A thread with plenty of details is available on the official forums!
