Another day, another Gmail Labs feature. You can now export and import your Gmail filters to and from a file, so you don't have to remember a complicated setup to get some good filtering. Getting it set up is simple. Navigate to Gmail Labs in your account, enable the Filter import/export feature, and save your changes. Now, when you navigate to the Settings -> Filters page, you've got a new Export button and a new Import link. Sharing a handful of awesome filters with a friend has never been easier.
