The inaugural True North PHP conference has been announced to take place in Toronto, Canada, on November 2 and 3, 2012. I have proposed doing a presentation on the Yii framework, introducing the framework and explaining what’s new in Yii2. To buy tickets to the conference, see the True North PHP Web site. To propose your own talk for True North PHP, head to their UserVoice page.
At the UserVoice site, you can also vote for what presentations you think are worth having. Even if you have no plans on attending, but would like me to give a Yii presentation, you can vote for my submission.
