We have a new feature called the zero replies view. It's what it sounds like - threads without any replies. Maybe it is a challenging question. Maybe a greenhorn just needs a nudge or encouragement. Check out the new view. Maybe you can be the one first one to reply.
Another new feature is that you can now specify what line number a code snippet starts at. This one is particularly cool because a rancher (Pawel Pawlowicz) suggested it and another rancher (Tim Cooke) did the research/analysis, implemented the fix and wrote the unit tests. All we had to do was integrate and re-test.
Oracle announced a new certification. And we have a new JSF certification forum for it. Granted not much is known since the exam went into beta so recently, but we're sure the forum will fill up.
