Sharing user sign-in data across several Vanilla forums
I have found that other users were asking for something similar, but no existing solution seems to exist yet.
Task: get users sign-in data in sync with several (2 or more) Vanilla forums installations. I.e., if user registers at one of the forums in sync, they should be able then to log in to every other synced forums using the same credentials (and if credentials are changed, the same change should be propagated across the forums in sync).
Has the above a known solution, or I should implement that myself?
