There are probably 5 different ways to do things. I use my main focused. Then my alts use /cast [target=focus-target] DPSSpell (for damage) and /cast [target=focus-target-target] HealSpell (for heals). I use HotKeyNet (www.hotkeynet.com) for my key broadcasting. It is very simple and efficient. I just got, and so far love mutiboxer. I use it mostly for following. It tells me when people are following and when they aren't.
