Right now the project works like this. When a user writes something to the notebook, the message is added to the end of the URL so that it can be read. The message is then written to the SD card (because the space on the MCU is not very large). The server reads from the SD card, and then writes that information to the page.
Now all that is left is advertising and getting people to use it. I have several friends who are currently freshman, and I will get them to spread the word to others who will still be around next semester. I also really like the idea of creating posters around school with a simple message asking for people to share their secrets.
