O.K so I have been giving this some thought last night and I have thought of a new solution. If I was to place 2 links on my site, 1 link for the original site and the 2nd link for the new site. Now depending on what link is selected would depend on what links are shown in the menu. All this would run form the original install of DNN. For example:
User clicks a link for GW1:
Menu reads: News, Resources, Information
User clicks a link for GW2:
Menu reads: Articles, Trade, Forum
This way if I keep it in 1 portal I only have to keep track of roles in 1 portal and not 2. So does anyone know if this is even possible?
