I think the registry should remain alphabetical, but the option existing to "pin" an official server to the top. As well, requiring servers to register to display on the registry could remove some problems. Remaining alphabetical would prevent a NetBattle-esque fiasco. Being able to "pin" or otherwise force on the top of the list would allow people to reach the Beta Server more quickly. The more users who play while the server is in debug mode, the faster bugs can be fixed.
found it at last! I just wanted to point out that there are more and more servers coming up by the day, and finding the beta server is becoming a pain (I've resorted to using "Advanced connection" more than half the time) so I definitely think it should be pinned on top. and perhaps its font should be in Bold since it is the main server, after all.
