Bottom line: If someone arrives to my site via "www.syracusefan.com", it appears their login doesn't stick because the login defaults to "syracusefan.com".
The simple solution is for people to only use "syracusefan.com", not "www.syracusefan.com". And knowing that a super majority of our visitors define the term "simple" ... this should solve the problem. But it won't ;-)
Is there an idiot proof solution you can think of?
EDIT: I just noticed that www.xenforo.com forwards automatically to xenforo.com. This seems to solve the problem here.
Can you point me in the right direction as to how to do this for my site?
