Personally, I'm right there with you OP. It bugs the hell out of me when people act like douchebags and just tell you to search the forum without answering your question. They are in this FORUM to read and reply to posts afterall. If they don't want to reply to threads, don't reply, simple as that.
The JB scene changes all the time, a thread from yesterday could easily be outdated. Searching through 8 pages of a thread is annoying when all you want is an answer.
So the answer is no, there is no JB out yet and when one does come out it will most likely be the most discussed thread in the forum.
