Translations:Do not hack MediaWiki core/10/en

The MediaWiki core has been designed to be modular, so there should be no reason to hack it. If there is a feature you want and it cannot be accomplished outside of modifying core, consider developing an extension or submitting your hack as a patch. Submit a bug report and tell the community the feature you want to accomplish. It will then be tested and your feature may become a part of the MediaWiki core.
