I have several different scripts on different subdomains each with its own login and database. I would like the user to be able to sign-up once and be member of each script. There would be several different subscription levels. If the user upgrades their membership the membership level would have to upgrade appropriately in each script. Basically I would like to have : www.site.com forum.site.com blog.site.com store.site.com etc.site.com Would I set-up amemberpro on www.site.com or amember.site.com Can this be done with amember? What would be the best way to set this up? Any help appreciared.
