Free software for learning Greek

At the Greek Study Day here on Wednesday, there was some discussion of memorisation. One thing that got mentioned was the number of useful little programmes for learning vocabulary and so on; and it was nice to hear the NT Gateway mentioned in this context. In the light of that discussion, I've just run a check on all the links on the Greek New Testament Gateway: Computer Software page and all are functioning fine. I've dropped the last two, however. Harry Hahne's Computer Assisted Bible Analysis review is now so dated as to be useless so I've deleted the link. And Drew Berkemeyer's Greek IQ Flash has now become a commercial service renamed i-Know It New Testament Greek so that link has been deleted too in line with my policy only to link to free materials.
