Update, 10th of March: If you've been picked, you should receive a PM on the Cyanide forum today or one of the upcoming days.
It's that time of the year - Cyanide is now looking for beta testers to help out with finding bugs in the upcoming Pro Cycling Manager 2010.
The main focus this year is testing of the new graphic engine, especially when it comes to the stability. For the same reason, you don't need a super-configuration to take part. Having time and motivation to test is the most important.
Other than that, there's also the usual testing, e.g. checking the new features, feedback on the AI changes, etc. - so all in all, a quite serious task. If you're up for it, have a look at this thread.
