There are several ways how you can contribute to the project. Any one is welcome and equally important!
The power of patterns comes from their solid connection to practical reality. No pattern is a pattern if it has not been tried successfully, and is not continuosly practiced. The job of a "Pattern Testpilot" is to try the patterns in reality and give feedback to the author.
The more people see and read a pattern, the better the pattern gets. This is especially true for the non-native speakers, who have to write patterns in a foreign language (namely English :-)). The Job of a reviewer is to read patterns and give the author feedback on content and language and form.
Of course, somebody has to write the patterns. Obviously, this is done by authors.
One of the big problems of the project in its current state is, that nobody knows it. It is therefore crucial, that we gain more publicity. If you like the PPP and want it to succeed, why not advertise in a magazine by writing a anticle or a column, on conference by giving a talk or a paper, in training companies or university by showing people the website, etc.
