Javascript enabled?

How can I find out if a Guestbook has kept Javascript/HTML enabled?

I don't want to find out by putting in a code though because once you submit a message it can't be deleted and I would look like an ass if it didn't work.

Try posting a non-malicous script, such as color or bold or something, then it wont look suspicous

<b>wow this is bold</b>

wow this site is <b>awsome</b>

then that will reduce suspicion even more! :ninja: stealth hacking…..
