You forgot to mention the most important thing in your post.  Anybody who
visits and uses your archive should contact you directly for any support
issues they have with using the software.  This list can't entertain 
questions or help solve problems for those using software from your 
archive.  You do have wording something like this at your web page but 
you know no one ever reads documentation. ;-)

Good luck!
