Dear Garmin
Please install a forum anti-spam mod. They are free and will virtually eliminate all these kitchen spam posts. The one you want hooks up with the www.stopforumspam.com spam database. Other VBulletin forums use it. I use the Invision Power Board version at my forums and get NO SPAM.
Pretty sure what you are after is here:
