Font Awesome is permitted in the Plugin Repository

This took longer than we would have liked to say, but there were communication issues on multiple fronts.

You can use the Font Awesome font files and CSS in your code, per the current Font Awesome License:

As far as crediting is concerned, we feel attribution is always good. You should always put that in your source code, but your readme is optional. Credit links must be opt-in if they show on the front facing part of your site (this includes the login page), but that’s nothing new.

So with that said, we’re going through the plugins that had been closed for Font Awesome usage and opening them. If we missed yours, please email us at plugins at wordpress.org, with a link to the plugin (like http://wordpress.org/extend/plugins/font-awesome/ which is open) and we’ll check right away.
