I've been asked several times if there is an IGNORE function to disappear posters you don't want to read. YES there is and it only takes a few seconds to banish forever.
You have to be logged in, of course. Then click on the User Control Panel (UCP). Its near the top on the left - just under 'Board Index'.
Friends & Foes is the rightmost tab of the UCP. Then click on the left tab 'Manage Foes'. Simply add your poster's name et voila!
HTH,
