The most likely times to find people in mudchat are early evening UK time and early evening US time - but for UKers that means looking in V.Late.
I could also be accused of lurking - I have in the past been the only one logged in for about an hour before anyone comes in and I just open a new web page and go back and check the chat room every 5 mins or so.
