Looking for 4 character domain names that are available on 123finder.com - trying to find something that could be an acronym for us. 4 letter domains are all taken, so these will all have to have a number or a hyphen in them. See some samples below:

zk2k.com - (ZoomKnowledge 2000) (Zip, Zap, Zone) -upon further review there are a lot of "2k" domains available, so I guess that was like 10 years ago huh?
wim4.com - (don't know what it could mean, but thought it was catchy)
vd0s.com - (that is a zero in there)
up1l.com - (up 1 learning?, up 1 level?)
t2hp.com - (train to higher p..?)
t2pl.com - (train to ...?)
te4y.com
onu1.com
on-5.com
no8t.com - (number 8 training? no 5 7 9 are also available)
my5p.com
myy1.com
mr0n.com - (Moron.com!!! I love it!)
m2y2.com - (me too you too??)
l10c.com - (level 10 computing)
kb-l.com (knowledge base learning)

Alright... I guess I don't really like these enough. Maybe it can get some creative juices flowing so I'll still post it.
