We received an e-mail from WebSense today--they've moved TalkLeft out of the "Adult Material: Sex" category and into the "Advocacy Groups" category (The site you submitted has been reviewed and the master database has been modified so that it will be filtered under the category of Advocacy Groups. This update will be available in the next database published.). Looks like the changes have been published, as I can now access TalkLeft from the office. Coolness.
For future reference, this form can be filled out to recommend changes to the WebSense database.
