WowAce

That addon will write in a emote form in the chat your "status".
Your "status" could be:
- something remarquable you just did (examples: honor kill, kill a Boss, did you best crit ever, acquired max. skill level in a profession, etc.)
- something about your statistics (HP/Mana/Energy...) : like, for example: telling that you need heal when your health is low, telling that your mana is low (useful in raids), etc.
- a custom sentence that you define yourself.

(first addon, just a try)
