Lionbridge Task Availability question--morning vs night?

Hey there,

​

So, I'm in the US. Eastern Standard Time. I tend to do my LB stuff at night because I work full-time during the day. Just wondering, are the bulk of tasks--like where you can work for hours straight if you wanted to--happening in the middle of the night/early morning to afternoon? Or is it just completely random? I might need to start working in the middle of the night. :-/ I usually average about 13-15 hrs/wk, but 20-24 is better. I can never achieve that, though, especially if I procrastinate til the end of the week/weekend.

Thank you!
