I registered this pretty much immediately after playing around with it for 30 minutes. I use it mainly for downloading and extracting binary newsgroups (Seinfeld!) and it works very well indeed. It seems to hog CPU a little bit, but I do only have a G3/400 graphite iMac DVSE. I do still retain MacSOUP as my primary newsreader mainly because of its interface and graphical thread display which is indispensable. Thoth is throughly recommended.
