The day many ex-TDZK players believed would never come has passed, as Fleets has entered private Alpha testing. The first wave of testers have been invited, with a second wave to follow shortly.
Although the blog states not to ask the admins for consideration as a tester, your BEST chance of becoming a tester is to join the Facebook page for Fleets.
Lastly, I do NOT want to hear whining about why you weren't selected as a tester. Take it elsewhere.
