Ingo Renner presented on the TYPO3 community and the EXT:community extension. The presentation discussed how communities are important for open source projects. It introduced the EXT:community extension, which is being developed to provide community functionality for TYPO3 sites. The extension uses an MVC framework and is designed to be flexible and extensible. Future plans include adding backend modules and migrating to Extbase and Fluid. The community is encouraged to contribute to the project.
