I want to ask basically two questions:
- Does there exist something like a "main" chatroom associated with each SE site?
- If it does, does it have some special status as far as freezing/deleting inactive rooms is concerned?
I think knowing about this might be useful for SE users. And I did not find any documentation about this. (Maybe I was not looking carefully enough.)
I have noticed that for a new SE site a chat room is created automatically by some kind of bot and it starts the room by saying:
Welcome to chat for: (name of the site)
This is a general discussion room, but please feel free to create more subject-specific rooms (a single room with every possible discussion isn't very helpful)
For playing with chat features: Sandbox
and remember; please read the FAQ ;p)
I did not find any official documentation for this, but I guess something like this is done for any every site, so every site has some associated "main chatroom".
On the other hand, I have seen this old comment:
The "main" chat rooms are actually just a normal chat room that people have created and then decided is the main one, the system doesn't have any concept of a "main" room, so they receive no special treatment.
Of course comment is quite old, the information contained in it might be outdated.
I have also seen in the question containing that particular comment (it is a feature request Exclude the main chat room from automatic freezing/deletion), that it happened that a main chat room for DIY.SE has been frozen fro inactivity. When I looked into the post from meta.DIY which was mentioned there, the answer there indicated that at least one room is always kept open for each site:
We do try to keep at least one room open per site, but it looks like some 1:1 rooms (question-related rooms between a few users) were taking precedence. I've changed it such that after the next build those 1:1 rooms will be excluded when considering room pruning (when it asks: "is there a more appropriate room to forcibly keep alive for this site?")
I have also found this post Don't recreate the main site room after deletion, which indicates, that the main chatroom can be even deleted.
Based on the information from the posts I have linked above it seems that the answer could be: The SE software keeps always one room for each SE site alive. But no particular room is chosen as the "main" room for a site.
However, as those posts are quite old and one of the posts I quoted also said that there was going to be some change in chatroom pruning algorithm, I would like to know how the things work now. (Depending on the answer, it is possible that the feature request I have mentioned can even be marked status-completed now.)
