This is just a list of volunteers for people who want to "announce their presence." There is no requirement to list yourself here. Some people just want to say a bit about themselves, and so here they are.
Participation on the project is via the mailing list and the source code repository. The most frequently asked question is "I want to help, how do I join?" You join by joining the mailing list, and by participating in discussion. You help by contributing your ideas, enthusiasm, code, documentation, tests, and intangibles.
The ASF welcomes all of you, whether listed here or not. The fundamental tenet of the ASF is that Great Communities build great code. The emphasis is on Community; the code comes from that. If you want to help, just join the mailing list, see what needs to be done, and do it.
