This week's book giveaway is in the Java 9 forum. We're giving away four copies of Java 9 Modularity: Patterns and Practices for Developing Maintainable Applications and have Sander Mak & Paul Bakker on-line! See this thread for details.
The Java 7 cert has been out long enough that it makes sense for it to have a wiki page that isn't called SCJP. I created the OCPJP FAQ page for Java 7 the cert and up and we already had one for OCAJP.
The great thing about wikis is that anyone can edit them. To provide a little motivation, I'd like to try an experiment. If you edit the wiki (in a non trivial manner) and post a reply in this thread saying what you changed, I'll give you a cow. (Or possibly multiple cows depending on the amount of work you do.)
