I'll be doing an Introduction to jQuery tomorrow at our local user group. It will cover a bunch of goodies including the basics, Ajax and extending jQuery. The talk will be pretty much the same in contents as the one I'll be giving at BASTA in about 2 weeks. Obviously tomorrow's is in Spanish :). There's already 25 people signed up and although there's limited space, feel free to come by even if you haven't signed up. We'll finish off the evening with a round table discussion.
