Read the 'New Computer' thread at http://www.worldcommunitygrid.org/forums/wcg/viewthread?thread=1150 . If you have your computers networked then running the Network Wizard ought to establish 'Internet Connection Sharing' so that you can access the Internet from both computers. Then you can download and install the WCG Agent normally. While installing, during the login process, check the box on the screen that says 'Previous member', then use your normal login. Instead of telling you that the Member ID is already in use, it will add the second Device ID to your Device List. Then the points from both computers are assigned to your Member ID.

I do not have 2 computers, but if you have questions, there are many members who can walk you through it. Just describe your systems if you need any help.

Best Wishes,
Lawrence
