Yeah, we have heard that from several others too :/ I have no idea why it's happening. Anyone who knows how to solve the problem?
Could it be because your page is almost entirely a list of links? (not saying that's bad, personally)
You could try contacting Websense: What you can do if you feel a website has been incorrectly categorized. ... You can also suggest that Websense researchers reevaluate a categorization by e-mailing suggest@websense.com.
I'll send them an email. Thanks!
