Rails_xss Plugin I installed the rails_xss plugin, for the main purpose of seeing what will break with Rails 3.0 (where the behaviour of the plugin is the default). I think I've fixed everything, but let me know if you see stuff that is HTML-escaped, which shouldn't be. As a side benefit, we now use Erubis, rather than ERB, to render templates. They tell me it's faster ...
