According to these two posts (one from the Zend Developer Zone and the other from php|architect, respectively), the Symfony project has a new resource for developers working with the framework - the Symfony Forge.

Symfony-forge is a site dedicated to symfony plugins, software, and the community of symfony users/developers. Here you will find complete api documentation for all plugins, a growing database of plugins to work with, and other tools to help organize and guide the plugin development for symfony.

The project, started up by Jonathan Wage and crew at CentreSource, is officially in beta and will remain as such until the move off of symfony-project is complete. There's already tons of plugins and applications listed on the site in lots of different categories including: Javascript, User Management, Media Assets, Performance and Security.

Be sure to check out the latest news about the site and subscribe to their feed to be kept up to date!
