SpamThrottle for World of Warcraft
I’ll occasionally be mentioning some rather great addons.  For the first of this series, I’m going to be telling you about SpamThrottle.  First, let me bring this all into context. A lot of the multiboxers here play on the Blackrock-US server.  Its one of the oldest, most-crowded, most-competitive servers that Blizzard has.  There are raid PUGs forming for everything from old world content, to the weekly raid quests, to heroic farming, to even Trial of the Grand Crusader and the new Icecrown instances.   Until 3.3, the best place to find and build a PuG was the Trade channel.
