Vanilla Forums 2 has been released. It is a simple, lightweight, open-source forum software that support add-ons and customized themes.
I was looking for a bbPress forum alternative (lightweight, highly customizable, open-source, etc) and I found Vanilla Forums.
I have tried Vanilla 2 beta for a couple months. It is exactly my ideal forum: simple, clean, focus on threads (instead of forums), support add-ons and themes, etc.
Why not bbPress?
bbPress is great piece of open-source forum script backup by WordPress but the development is toooooo slooooowww.
The latest stable version of bbPress (version 1.0.2) was released 1 year ago! Matt Mullenweg, the founding developer of WordPress, was only recently updated bbPress blog, 7 months 2 days since his last post.
Once, I almost thought bbPress was dead…
Therefore, Vanilla Forums with active developments and strong support forums is my pick of lightweight forum software.
P.S. It is easy to, too!
