I suppose there is no real best way to release untested files in such communities unless an admin has approved. Someone might suspect that you have tampered with server's coding to steal personal info, and it would be hard to prove them wrong.
A bit offtopic but... is it really neccessary to release a new subsubversion of Voltz every couple of days instead of gathering all major fixes on less frequent updates? I understand that it must be at least playable before focusing ahead, but people seem eager to start servers already.
Back in topic, i'll take a look at your build, see what was fixed in this update if not for any other reason.
