As announced earlier, we are organizing the first code sprint for Symfony 2.3 tomorrow (Friday 12th). If you want to participate and want to prepare your day, have a look at this document where we have listed all current opened pull requests with their current status.
Jean-François also tagged all current opened issues, so it is really easy to have a look at issues for a given component.
Last but not the least, many Symfony core developers will be available the whole day to help you. Let's meet at #symfony-dev on Freenode.
The sprint day is tomorrow (friday), isn't it?
That's bad, I don't think I can help (until late in the evening).
+1 for code sprints!
I'll be there as well. I must learn and test Symfony2 a bit more.
I made a typo in the blog post: The IRC channel we are going to use is #symfony-dev, not #symfony.
