The entire source code is available on the ThinkJot Subversion Repository. You can always download the latest source code by using a Subversion client (like Tortoise for Windows).
Contributing Code
* If you are making minor changes, I recommend that you download the latest source code from the Subversion Repository above, and send the changes to jeswin@gmail.com.
* If you are planning to spend more time on developing ThinkJot, and making extensive changes, I can give you Subversion commit access. This will allow you to make changes directly on the version control. We need to work out some code review mechanism before that.
Contributing Money/Paypal
* Sorry, not accepting money ;)
* Maybe later, when I can spend more time on ThinkJot :)
