Wow! Thanks so much for all the info.
Yes, I do start my Z HITs at 8am. In fact, the collection sound of the Zs is now my morning alarm clock. I had noticed that turkers in this forum started talking about Zs around that time, so that's how I'd been able to snag as many as I did this week.
With the Zs, some I can get through quickly, while others trip me up. In the beginning, I was spending about 3 minutes per HIT, but I'm trying to drop down to 30 - 40 seconds per. I still get a little confused when I have to select the goods and/or services, the category the g&s falls under, and the direct, indirect, or both options. I just need to keep doing it more and more, I think.
Panda Crazy does have a "Pantha" button. Maybe I should select it and see what happens. I'm still new to Panda Crazy, so I'm continuously trying to figure out how to use it correctly. Maybe I'll look into Pantha Collector if Panda Crazy bums me out.
Good to know about the Masters. I'd always been curious about that title. It's just that I sometimes see some really good HITs, but they require a Masters qual. If it's not that important, then I'll move on.
