Enable posting of unfiltered HTML in a Multisite environment, configurable on a per-role basis.
This plugin allows blog administrators in a Multisite environment to specify user roles which are allowed to create posts with unfiltered HTML. These users will be able to make posts containing
<embed> etc without that content being stripped by Multisite's sanitisation rules.
The plugin can either be used globally for your entire network, or it can be applied on a blog-by-blog basis. Regular WordPress already allows this feature and does not need this plugin. (more)
