Mozilla Foundation looking for Web Developers (volunteers)
If you’ve got the spare time and looking for an interesting project for your portfolio (i.e. work for free) see here;
We are looking for three programmers who are proficient in Perl or other web apps languages and can volunteer their time and skill to help us build the tools we will need to make three upcoming community marketing campaigns successful. These are some of our most exciting campaigns yet and promise to net us hundreds of thousands of users if executed properly. The work that’s needed is simple and should be trivial for anyone skilled in perl or other web apps languages. Please send mail to blake at cs.stanford.edu if you are interested and would like more details.
PHP fits in that “other web apps languages” category ;)
