I joined a NING community called Living In Black at the beginning of the year and I sincerely regret doing so. Although I have closed my account MONTHS ago, I still receive emails from random strangers on a daily basis marketing their events, groups and messages. I am pissed off to the point of pissedoffity. I hate spam. I advise you NOT to join any community like this one unless you want your email passed around like a fat joint on April 20th.
SHAME ON YOU!
