Sponsored by Monotype Imaging and Fonts.com,
the Web Fonts plugin provides an administrative interface for browsing and applying web fonts from a variety of sources. The plugin
includes support for web fonts from the Fonts.com web fonts collection out of the box.
In addition, support for Google Web Fonts has been added
in Version 1.1.0. You can now browse and enable any of the many open web fonts available from Google and then add them to your
stylesheet the same way you do with Fonts.com web fonts. Other web font providers will be added in the future via plugins.
If you run into issues with the plugin, please open a support topic on the WordPress.org
support forums.
