The format of the contest is interesting: you must submit a twenty word reason why you need to win the software. “Winners will be selected based on humor, wit, and verve,” which might exclude a few pastors, it is well worth the effort to win this rather generous prize.
BibleWorks 9 has some excellent tools for working with Greek Manuscripts, including a Greek Manuscript tool which allows the user not simply to see the evidence for a variant, but to examine the actual manuscript. Several key manuscripts are available, including Sinaiticus, Vaticanus, Alexandrinus, Bezae, and Washingtonianus. You can see the Manuscript tool in the picture to the left.
You can enter on their Facebook page as well, but all entries must be in by June 15. Good luck!
