Looking for inspiration I have found myself re-reading old solutions that I had written. Some were good, others not so good but in aggregate I was proud of my work. What struck me was the time it took to hunt each one down from the various rounds, therefore I thot it useful to create a central repository for all us to maintain a running record of each of our solutions. Perhaps this will be useful only to you, but I think everyone at GWC will appreciate being able to quickly peruse prior solutions people have submitted.
Organize however you like, you definitely don’t have to do it exactly as I do. Enjoy!
