Tutorial discussion form not working

[nullbarriere]

I wanted to help to keep the JCache Tutorial (http://dev.joomla.org/component/option,com_jd-wiki/Itemid,31/id,tips:using_caching/) up2date, but the "discussion" form keeps accusing me of putting script into the fields, which was kind of true in the beginning, since i wanted do help out with PHP script snippets like this:

Cleaning the cache
As of RC4 JCache implements clean(); instead of cleanCache();

Please tell me, when the forms are fixed.
