If i'm one of them, I usually come on here about 11.00 ish your time whilst I trawl through my work emails, stay on til those and any ordering, phone calls etc I might need to do is done, hop off and get some real world time with my fam, drop back on to see what needs tidying up at the end of the day then hop off again and finally often jump onto Mamya's Goodnight music thread. I don't actually spend that much time here just hop on and off throughout the day when I'm already working on the computer.
If i'm filming or Mr Cal is home I'm rarely on at all.
