Rivlas and N2L - the problem with placing restrictions or limitations is I suck at them! I had Facebook years ago and deleted it simply because I just couldn't follow any self imposed restrictions. Even now I struggle with not checking the forums I'm on a million times a day .
I'm an all or nothing type of person unfortunately and am veryyyy very very (emphasis on very) slowly starting to get the hang of moderation.

Cricket thanks, the reasons you mentioned are some of the driving factors for deciding not to have a tele. I can get news off the net (not that I'm into news much anyway) and of course I'll have a computer for the kids to do their homework on. I really am not interested in anything on tv myself and neither is dh, the only reason I switch it on is because I can. It's there with nothing to do, I have nothing to do, and voila - a day wasted.
