I'm also on Act 4 and I need to work on it for another 5 days. I was very active at TT last year. I earned about $800, then I got burned out, so I stopped logging in for a while last summer. Things came up after that I wasn't able to get back into it again until about 2 weeks ago. I didn't realize the hunt was out there until about 5 days ago...after I already completed the Act 3 requirement 3 times in less than a week and a half!!! Then it took me 4 days to complete it again, LOL. I knew I was going to need the Act 4 stuff at some point, so I started working on it a few days ago. I also started working on my Amethyst this week. I found the diamond over a year ago, so I'm safe there.
There are parts of TT that I really don't like (e.g., surveys, since I take the exact same ones at other sites and get paid $5 instead of $.75, plus I don't have to waste a lot of time trying to qualify for something). I also don't like the cash shopping there, because I get a better percent back at other sites. I love TT overall though. I like the platform better than similar sites and I have more luck with getting approvals there. I also got lucky with some pearls and I have $290 in referral income!
