Ye' old general discussion board. Basically, for everything that isn't covered elsewhere. Come here to shoot the breeze, shoot your mouth off, or whatever suits your fancy. This forum is not for asking programming related questions.
For Messenger Services, see: http://grc.com/stm/shootthemessenger.htm for info and solutions. It can easely be turned off. Now keep to the subject of the original post.
Spam is usually something from someone I don't know and doesn't have anything to do with a programming job in mind (I can pick out if it's a spam message or an actual job request).
