I am not supporting the creation of in game chat but I would like to point out that 99% of the people I know who would be interested in playing do not know a thing about IRC and have no interest in learning. They want to play a game and expect all resources to be right there in the game. Of course, this is just my personal observation, others may vary.
All the same, I do not like the idea of a Training Continent or in game chat. Just my preference...
