No, I checked the profile after the day passed, and second day, and again. It wasn't 10 minutes.

Just compare date of the above question and date when this thread was started.

Yes, now it appeared., thanks.

But what was the problem? Smth DB-related?

The functioning of SCN is quite clear, but that don't contradict with the idea of chat. Check SO implementation. Joining chat is always voluntarily but nevertheless those who are ready to help always can help.

Similar thread already started.
