Hi Michael,
When did you sign up for TextFugu? Did you pay for a Lifetime Membership?
This site has been dead in the water since at least 2015, probably earlier. It was started in 2010, I joined in 2011, and it was great for a few years. Koichi kept moving onto newer and shinier things and eventually abandoned TextFugu completely, half-finished. It seems like TextFugu’s replacement – EtoEto – has also been abandoned in alpha stage (no updates since 2017).
My suggestion is ask for your money back and find a better resource to learn. Tae Kim is a good one if that’s still around, though there are probably a ton of new options that weren’t around when I started so take a look.
