When *censored*tail was first released, it was a killer app in its market segment. I paid for it and used it regularly, and happily. Nice, clean interface, easy to use, etc.—and worth the price. Since then, it's been downhill with a tangle of badly-timed, ill-defined, and questionably upgradable releases.

So now I (again) try to run the gauntlet of upgrading to the Leopard version… It forces me to reenter my original registration, so I duly dig it out from my email archive only to discover that it's not accepted. I'm sure as h*ll not going to bother with trying to contact the developer or to pay up again. What a hassle. I'm switching to Onyx, which is free, better supported, and better. Good riddance, *censored*tail!
