“Vanilla is an open-source, standards-compliant, multi-lingual, theme-able, pluggable community forum.
Over 350,000 sites use Vanilla Forums to manage feedback, spark discussion, and make customers smile.”
There are competitors ranging from bbPress, phpBB, and punBB (like others we’re torn between bbPress and Vanilla – the proxyConnect plugin allows us to integrate Vanilla with WordPress). But Vanilla is a leading solution offering a great user experience, simple customization and hosting with a large user community. Plus they’re funded by our friends at Montreal Startup which makes them an easy choice.
