The name LeberMac is wrong on a number of different fronts.

I call for the devs to rename his account

LeberWac

Seconded.

Yes, I'm actually feeling physically ill after pushing through the order today. It's a rather big change.

I've been bugging Momerath to change another name for me for a while now, I'll think up a suitable creative alternative for LeberMac.

Momerath: This is the kind of thing best decided over several beers and tequila shots. Hint Hint.

But, I'll take suggestions below.
We've already had:

LeberWac
LeberPC
DarkLeber
EvilLeber
Lever2000 SP2

Keep the suggestions coming!

I think the subtle inversion of the 'M' that 'LeberWac' uses makes it the best choice. That said, 'LeberOSTraitor' has a nice ring to it.

mm... well, I've heard the name Lindows isn't being used anymore...

or, perhaps:

-OpenLeber (commodity hardware ftw!)
-LeberCool or LeberFrost, 'cuz that's how hot the new box'll run :D
-LebAgave?

or, maybe just:

Leebs

LeebsXP

Plain old... Leber.

Er, Gregndows. Or maybe just Gregdows.

CuervoLeebs

LeebvoGold

Jose Leebvo

Leber Cuervo

that's pretty much all i got.

Lebertarian

Lebertine

LeberHosen!

Lebiathan

Leber on vista:

Greg Windozer

or if you decide on Linux:

Lebuntu

LeberDoze gets my vote!

This is a bit long but....

*Windoze user formerly known as LeberMac*

:P

Leber*
Is it even possible to get an asterisk in the name?

WinLeber

Makes you sound kinda desirable... Besides, I think there's an unwritten law where Windoze has to be mentioned first. Ego thing perhaps.

Or, I like Aleksey's idea, but it should be Leebiathan
