The Tempus Project has been open source for many years now. The hopes and intentions for it were always to give others a leg-up to get started building web-apps like i wish i had as a kid. There were so many tutorials and ideas, expansions and plans for the project. Unfortunately no person is given unlimited time to accomplish their dreams and over the years the idea for a huge repository for learning and education has taken a back seat.
At this time, the best recommendation available is to contact us for more information. The site here is actively maintained so feel free to utilize any of our available resources for contact. In addition to the site here, you can contact the lead developer (me) directly through JoeyKimsey.com.
Right now, this entire system was built and managed by myself. As stated, I have used my own version of this for years, but translating it to a publicly available product is not a 1-to-1 job. There may be bugs or issues encountered while you use the product. I can't guarantee a fix for every need in every case immediately, but I do actively keep track of bugs and work hard to ensure everyone has a great experience using the app.
If you encounter any bugs, feel free to report them here. Likewise, there are forms for feedback, reviews, suggestions, and a general contact form. Thanks for taking the time to check out the product!
