Contributing to the MySQL User Guide
The MySQL User Guide is worth looking at. Its not the reference manual (which is excellent – kudos to our Documentation Team). Its target audience are users that are new to databases or users that are new to MySQL in general.
What’s really interesting about the MySQL User Guide is that you can help shape it. You, the community, can participate in writing it!
I for one, know that this is the easiest way you can start contributing to any open source project. Documenting it. Soon, you will realise that you’ve become an expert (writing documentation, or giving training, will always keep you sharp). Some move on to then delving in coding, some go on being consultants, and some end up being hired by the company that sponsors the project ;)
