Looking for a Witch Farm

I would very much like to use a witch farm. I was wondering if anyone would let me know the co-ordinates of one they have built or that they are using. I would use it only when nobody else is doing so.
Serious replies only, please.

If it's glowstone and/or redstone you're looking for, you may also consider a gold farm and trading the zombie flesh with a cleric. Witch farms in EMC can be a little slow going (20x20x16 2 spawn limit and other limits for lag), but villager trading is a bit OP here. You may also find a gold farm owner that has a stockpile of flesh they have not the time to trade.

Thank you. I will keep that in Mind.

I realize hours later that other people say my previous post when they mean: No. You are silly.
But I mean it as: That seems like a Viable option.

emc is also happy enough to provide a list of those with good quality gold farms (at least the xp ones) here:

heh, ok, they are not all gold farms, but it's pretty likely.

I'ma Probably use the SMP8 one. Because I Practically live there.
Tee hee <3
