So, I am about to put up the code for my mods to nProbe. I believe it runs on 64 bit. I really haven't done any work on the hashing part, but I am sure that the work that Luca Deri has done works well. How do you put a public git repository online? Somewhat like the following. http://www.gtk.org/download.html I found the following link. Does it look like it has the correct details? http://toolmantim.com/thoughts/setting_up_a_new_remote_git_repository brian -- Brian Lavender http://www.brie.com/brian/ "There are two ways of constructing a software design.
