[Plugin: Google Website Optimizer for WordPress] using Google Website Optimizer plugin with MU

I installed this plugin on a MU installation and couldn’t understand why the <script>utmx_section("Insert your section name here")</script> kept stripping out the script tags – but soon realised that MU strips javascript tags.

So I used this MU plugin and it solved the problem. http://www.binh.name/less-filter-plugin-for-wordpress/

I’m guessing you only want to use this if you trust your MU users not to install nasty javascript.
