All it actually does it add a tweet about the competition, that is if you enter the competition (one entry) by signing up your Twitter account. Personally I did it, got the entry, and then just removed the tweet. The entry stayed valid..
SCAN Computers is obviously one of the largest computer suppliers in the UK so they are not going to promote an outfit that starts messing with your Twitter account. It did make me wonder thought, until I saw the tweet they had done on our account about the competition.
Although good thinking - put people off as that way it will increase the odds of winning!
