Usually I check it right when I wake up, and then a couple of times durring the day. I have a laptop, so instead of reading in bed, I web surf in bed, and I always check MiceChat about 50 times before going to bed to see if there are any updates! :-)
No offense, but I check in when things are dead at another non-Disney board I post heavily to. Which is to say I pop in maybe once a week. I'm sure as I get to know other people here I'll make more frequent stops, but for now I'm just getting started here.
