Ummmmmmmm yeah - I've done it....often!
I log quite a bit of time on here daily! I do it from home since I don't have a PC at work (construction worker in the field 100% of the time!) So I quickly jump on as soon as I get home, do the family thing for a few hours, and then burn late into the night on L-g as well as doing other PC work.
The only time I'm really 'away' from L-g is when I take the family camping...and now with my new iPod I may get a signal there too!
