Now that Smalltalk Solutions is co-located with LinuxWorld/NetworkWorld, you'll need to register earlier than you're used to - it's a big show in its own right, and the Blue Jays are in town when the show is being held. Make sure you book early - there are a lot of people attending this show. If the baseball schedule interests you, here's who Toronto is playing at that time:

April 18 and 19 … New York (before the conference)

April 21-23 … Boston

April 25-27 … Baltimore

So register now, and make sure to arrange your hotel!
