This week's giveaway is in the Java/Jakarta EE forum. We're giving away four copies of Java EE 8 High Performance and have Romain Manni-Bucau on-line! See If you want to implement a discussion forum like JavaRanch's Big Moose Saloon, I suggest that you go to ultimatebb.com and buy their software. It's a coupla hundred bucks. Good stuff! Then, find a site that runs Perl and install it. The software vendor will install it for you for a few bucks more.
I'd agree with Paul. I'd love to see a Java-based BB that's anything like as nice to use as UBB (the software used here). I got to a lot of sites with "discussion areas" and most of them are complete rubbish - hard to read, hard to post to. When I get fed up with other boards, I ask them to look here. I don't know if they do, though.
