This feature-request is primarily related to programming languages used in Stack Overflow, Code Review, Super User, etc.
I am a heavy Stack Overflow
VBA user and browse and answer
VBA questions almost exclusively. For a long time as I built up my reputation, I wondered why Stack Overflow did not have a chat room to discuss
VBA related mechanics and questions. It was not until recently that a member of the
VBA chat room on Code Review invited me to join their chat room for regular
Because programming languages and the discussion on each can span multiple sites, could we develop a way to link a single chat room to multiple SE sites? In my opinion this would encourage more active participation in the chat room because a user would only need to be active on ONE site to find the room. I sincerely dislike the idea of having multiple chat rooms on multiple programming related sites for the same language (splinters the group of enthusiasts on that one language), and most of the languages themselves do not justify their own SE site.
Edit: Based on Comments: I'd switch my request/question to can we migrate SO chat into SE chat and allow a room to be "tagged" with multiple parent SE sites.
