This is an updated version of the Alamo mod for Druids. I won't claim any real authorship for this great mod - that goes to Valanduil of LightningHoof, I simply updated it for TBC. The blurb below is copied from the original posting of the mod on ui.worldofwar.net.

Alamo teechs u 2 play DURID! And this addon helps you and your friends learn! Alamo (the addon) detects shapeshifts and announces to one of many possible chat targets (whisper, say, yell, party, guild, or raid) a bit of Alamo's wisdom, as it relates to your new form. For example, if you shift into bear form, you might say aloud, 'Tehm whos bare durids, can B 4 tank.'

The chance of the addon actually making an announcement can be set as a percentage, so that, for example, any given shapeshift might have only a 35% chance of causing an announcement. This is an important feature intended to keep the addon's output entertaining instead of becoming spam.
