Hi everyone,

I have a few questions and was wondering if you could help me clearing some doubts.

I have discourse set up under a main domain and not under a subdomain. I have recently changed my mind and instead of having my forum categories in one place, I would like to have them set up as subdomains, my questions are:

can I set up multiple instances of discourse under one domain? As in, Category of computer, nature, life and science. Can I set up four subdomains and one discourse instance in each subdomain? do I need to remove discourse from my main domain?

Also, is there a way to link users between more than on instance? As in, allow users to have rep and other things per site but be able to operate as a single sign on in all instances? Similar to how SE is steup? Is this something possible?

Best,  
Roger
