I recently started an opensource project, called WOS (web operating system). It involves programming an advanced e-mail client, web browser, IM client and more, and linking them together. I am programming the version for Mac OS X, and we need developers who can program with either Linux or Windows, or both. We are setting up a website right now, www.woodleynet.com, but I'd prefer anyone interested to MSN me at email@example.com, message me on AIM at Woodley6453, or e-mail me at firstname.lastname@example.org.
Also note that if the project does take off, a donations center will be opened up, and the money earned from that will be evenly split between the developers.
