hello everyone it's my first post
so the case is when i tried 2 join certain rooms
an error message pops up:
this room has restricted entry to a specific list of users (rc-5209)

i really wanna join this one particular room
so please help
any would be grateful thx

That means that the owner of that room has restricted entry to only a few people on a list. You are not on that list. You cannot join that room unless your nick is on that list. But its not. So you can't.
