This room did not have much traffic so it probably not really needed. So I will stop keeping it alive. If such room is needed in the future, a new room can be created or this room can be unfrozen by a mod.
A new room probably wouldn't hurt. If it's needed.
On the other hand, I thought it is better to use already existing (albeit frozen room) than create new functional analysis chatroom whenever new topic for discussion related to this area appears.
@ArthurFischer I followed that advice. Namely the last part: "or this room can be unfrozen by a mod."
In any case, an alternative to keeping room alive is either creating a new room each time or asking a mod to unfreeze a room. (Which is what I tried this time.)
If needed we can discuss this further, but probably it would be better to do so in another room. (I do not want to fill Mods' Office with something which is off-topic here.)
But I will have to go afk soon. So probably not right now.
We were playing around with ignoring each other and he figures only mods can if a paticular user has him on ignore by looking on that users parent profile page.
I'm not sure if all the mods know about this feature...
