Changes are made at your own risk and are not guaranteed to work. Always make backups of the database and files prior to implementing hacks. Make a special backup of the file and/or template you are modifying so that you can roll back quickly.

Hacks are dangerous and can cause your site to stop working. They make later updates to ExpressionEngine more difficult; you should track your hacks for post-update re-implementation. 

Most hacks are unnecessary, please review the Development Documentation for information on expanding ExpressionEngine via Modules, Extensions, and Plugins.

Hacks are never officially supported.

There is a hack posted in the forums to include attachments when sending mail to a mailing list in EE.
