I want to implement this feature. I wonder if there are any solutions or ideas for solutions?
There are 3 types, Forum A and Forum B. C Forum
Then these three forums
-1. User information sharing, users in Forum A can log in to Forum B. You can also log in in the C forum.
-2, shared by some nodes. For example, one of the nodes in forum A may appear in forums B and C.
-3, three forums, each forum has its own URL, appearance and name. These are independent and will not be shared.
Is there any solution? Still an idea?
Finally, I am from China, and I hope that my friends abroad will pay attention to protection and maintain good health.
