Yes, it is old news, but it is great news that bbPress 1.0 is released. Another project from the creators of WordPress, bbPress is a forum script. It even allows you to integrate the forum smoothly with your website because the php call functions are quite similar.
bbPress boast to be lean code-wise, secure, and quite flexible. There are already many plugins created to expand your own personal installation. I have set up quite a few bbPress forums for clients and they have loved it. The most attractive is the security. If anyone has ever had a phpBB forum, you know it WILL eventually be hacked no matter how many times it has been updated. The core has never been reworked properly and of course, it is very bulky.
I am contemplating adding a forum onto Blondish.net for support questions, but I will be also putting a price on support as I am fielding quite a few. Most of them ask me to correct their installation and this takes a chunk out of my time. Most of these I do without being paid, so I have to put a stop on it. I will definitely be using bbPress for that forum.
I have been following bbPress updates for quite some time, and I am extremely happy to see another WordPress product out for people to use. I am hoping for our cPanel Fantastico users, that bbPress will become available as an automatic install. I asked during WordCamp Chicago 2009 about this and apparently it is in the works, though there is not a definitely release date.
