Sorry to bother you, I hope some users would come up with the differential manifolds in the respective chat room, I would still prefer asking in Differential topology chat room as in the main chat there are many chats going on and also I try to preserve the chats for future use and since the main chats are heavily used and they will be flood. may be wrong.

@user21820 I am not sure whether your Miscellaneous room was meant to be just a temporary thing or whether you plan to use it longer. I will point out that it is 2 days from getting frozen. (Of course, it can be unfrozen by a moderator again.)

@BAYMAX As I do not know much about differential topology, I will not be able to help you there.

ok

@MartinSleziak Thanks for reminding me. Yes I probably will have reason to continue using it to record crank postings before they get removed. It can also be my experiment to see what happens close to the freeze point. =)

@user21820 I am not really sure what you mean by "what happens close to the freeze point".

You have been active here for a long time, you must have seen many rooms which were frozen.
