Any Horde PvP Guilds?

Hey guys,

Just hit 70 on my lock and looking for a pvp guild if any are accepting new members. Been a while since I played tbc but starting the honor grind to start to gear up. Interested in eventually doing arenas and bg's.

Thanks in advance.

Also, to add on to this, how do I go about finding arena partners. New to it but want to learn.
