I am on a few folk's ignore list. I didn't know until they pm'd me with a "nasty" note and said I was added to their ignore list. Odd as it sounds, it really didn't bother me. Figured it is their choice. I don't use the ignore button.. I prefer to see what is going on around me.. I think just knowing the option is available is enough for me...It offers me a choice.. SO at this time, my "choice" is not to use the ignore option
