I am obviously already registered with TheServerSide.com, but when I attempt to register with TheServerSide.net with the same email address as .com I get the error
Required parameter subscribeResearch of component CrossRegister/subscriptions is not bound.
If I try to register with .net with a different email address, registration works fine. Obviously I would prefer to use the same email address for all TSS registrations.
Try it again it should work just fine.
