This is a shameless advertisement for another open source project that I think would interest some people here. Since my teachers haven't started assigning WikiTextbooks I wanted to at least buy and sell textbooks cheaper without the bookstore markup. I stumbled upon phpbookexchange: http://sourceforge.net/projects/bookexchange/ . Code for students to post the books they have for sale and the buy books from other students. From that code I made a few improvements and came up with: http://www.westernbookexchange.com/ It cost me about $30 to set up the site but I saved about $100 on my next semester of books. Now I am working on an improved version at http://www.westernbookexchange.com/test/books It is easier to theme and it has many user improvements You can download the code from the sourceforge page but it still doesn't work so I posted my code at: http://www.westernbookexchange.com/phpBookEx.rar just change the variables in mysqlinfo.php and your ready to go. I hope this might help a few schools David Degner
