If we don't have something to do "out and about" probably 10-12 hours a day x 2 because there are 2 of us, on 2 computers.
I would say on average about 5 hours, but some days can be a lot more, whereas some days can be just 10 minutes to check email. Haha, actually I would like some help in the future from people who are online often. All I require is for you to register on my website's forum and occasional refresh the page.... if anyone is interested in helping me, feel free to send me a PM. I'm open to any interesting exchanges you might have in mind. And, actually the forum may be interesting to some people, so have a look and contact me. Oh, here is the forum :daxueyingyu.com/forum
It really depends on the day, sometimes it can be many hours, sometimes I just check my mail, but I'm usually connected all day long, I like having the opportunity to just check something on the internet.
