there are programs that record mouse movements and clicks. you can record it and have it automatically click the Join button. You have to check once in a while that it's connected though (ps. I did not try this myself, but would think it should work)....
Hamachi is having a DDos attack with everyone trying to click on the join button. Must have clicked it 1000 times today.
Around 3 hours ... I leave the Hamachi window opened in my notebook and clicked 5 times each 5 - 10 minutes , while I browsing in another PC on the side. After the activation I make a backup of the tokens using the Advanced Tokens Manager from Josh Cell ... Thanks to Josh also !!!
