During the existence of Phex, many people have contributed to it.
Currently the core development group consists of gk and Arne Babenhauserheide.
Besides these two, several others actively contribute to Phex, like Lord of the Rings, birdy and the other moderators in the Gnutella forums who do really hard and good work and far too seldom hear a thank you. In case you're reading this: Thank you for your great work!
gk
Tasks: Lead programmer and project leader.
Description: (by Arne) He is the longest active member of the Phex team and coordinates the coding work. He knows the Phex code inside out, he's written a major part of it himself, after all.
He's calm and professional, and he has yet to make a wrong decision (I get to know of :) ).
And it's a pleasure working with him.
Contact: Come into the Phex Forums or into IRC: #phex @ freenode.
Arne Babenhauserheide
Tasks: Translator (de), Webdesigner, Forum Moderator, Tester.
Description: (by himself) He's split into many directions, but contributing to Phex has become one of the centerstones of his life. He's been part of the Phex Development Group since about 2003, and is happy to see the number of users rise.
He's a strong believer in the capabilities of Gnutella as the best p2p network and is the author of Gnutella For Users a guide to Gnutella for non-programmers.
If you want to make him happy, take a look at his personal Website with stories, songs, poems and strange ideas about various topics, including p2p, filesharing and politics as well as fantasy, roleplaying and science fiction.
