This is the big disadvantage that blurs the immense qualities of #rocketchat, this has already been much discussed because it is the same problem in dolphin, many have sought a solution to this but to my knowledge nobody could do it .
I left out for that reason, too bad. But currently it is a place apart in the site and because of the problem you mention, you get 500 people who pass on the day but never at the same time, so can exchanges in the end.
The question is, are you going to do anything to solve that?
