Ella, the sessions can start at any time but typically, we are looking at early evening in Mudcat (EST) time and they are 5 hours behind us.There are a few UK people who do open the room and you also could do if you wish to. Just PM me or speak to any of the admins in there when the room is open.
Amergin, it is possible that the person sending the PM was not aware of the problems this causes so I wouldn't react that strongly but I agree that it is disruptive and coming from anyone who knows the system can only be considered as being plain rude.
