I'm usually on all day, but have to put laptop on standby from time to time and I don't know if that logs me off or not. I don't think so as I don't have to log back in again when I de-hibernate.
I still have to constantly check the for sale section, this is despite me selling all my retro and that I won't have room for any more than the two bikes i'm keeping - but, just in case...
I switch the PC on or my I-Phone at about 5am every morning and thats me on for most of the day. I have work to do but the site is up in the office when i pop in to make a call I'll catch up. I sometimes browse in the car on the way home in traffic and then back on in the evening until 10-11. Sometimes if I can't sleep I'll log in too. Somedays are quiet so i spend less time on here and Sundays are taken up riding and doing the family thing but I'll be on by teatime.
