Just one private module so far, for the CC project. It was fun.
The drupal system is very comfortable for adding code yourself . The hooks allow you to enter basically everywhere in the build up process of the page. They are very useful, but the difficult thing is to know when they are called, and what variables can be set at each hook. So it takes some time to choose the right hooks for your project. That is why I will write down on this site some documentation about the hooks I use.
