Seeing all the selfpromotions up here, I'll try to give a somewhat objective view on the EU houses, although you probably know most of it.
The somewhat bigger EU houses:
UK
CC (judging by Jalau's post, you've been there before)
ON
Aegis
VLKA also seems to have some EU lately
The somewhat smaller EU houses:
DK (Dragon Knights)
SCK (Southern Chidean Knights) can almost put this one at the larger houses
Mighty Knights (bestest originalest name)
And a dozen more
The somewhat bigger German houses:
IRK (Inglorious Retarded Knights), pretty nice fellows, as far as I know
Probably forgetting a few here
The somewhat smaller German houses:
DO (Deutcher Orden)
WR (Wolf Raiders)
SEF (Swadian Elite Fighters)
DARK (THE_DARK_EMPIRE) yarr caps yarr
That's all I can find on a short note. Good luck finding the house best suited for you!
I was never here, you saw nothing...
Motivational tip: When you wake up in the morning, look in the mirror and say confidently, "That's a nice head you have on your shoulders."
