More documentation, more fun

Today I added a huge amount of code examples to the tinymail API reference documentation and fixed its Python bindings.

It would be nice if some native English speakers could point me to spelling fixes and/or make suggestions for the documentation. What is missing? What documentation do you people need more than what is available now? How can I improve it?

An overview of the available documentation:

Yet I still feel like something critical is missing. From the webstats I noticed people are also looking a lot at the source code of tinymail. That, by itself, is definitely good. However, is that because it lacks documentation? Please do tell me. Please do express your criticism. I want to know it. The target is, indeed, to implement the project better than perfect.
