I thought I would mention this although I understand if anyone cared or actually used jitsi the would know this already. But just in case. No one can chat with visitors that come to meet.jit.si because rape blocks are programmed to come up covering the chat. By the time you make them all go away it is too late.
Obviously coded by a disgruntled programmer sabotaging the software.
This has been there so long it makes you wonder if there are any programmers here that care.
