What are the app/code/local and app/code/community for?
- core: is the original code from Magento. Everyone recomend that you don’t have to change that code.
- local: your own modules or rewrites of core modules.
- community: extensions that you can doanload from magento-connect… or maybe any code that is not core and not local.
