Short Answer: Nobody, You Can.

I would like to give a hats off to some people
that have help in the past/currently:

James Keeline
The very first member and most active
in San Diego PHP Community
http://www.iteachphp.com/

Josh Penix
Top notch systems administrator
can do php, or anything else.
http://binarytribe.com

Jesus C.
A very advanced programmer/author, took the
time while working on high level bio projects
to give talks and help rookies.
(archives of talks will be back online soon)

Richard Baskett aka baskettcase
http://www.baskettcase.com/
Is in charge of the list (and/or anything else he wants.)

David ?
Kept it going with meetings a while.
Is now CTO for medical software Co.

People have asked to move site, or point somewhere else.
The only thing I have done is at least keep the site up,
and not let it turn into a search page. Ill admit sometimes
its slow and go with maintence, updates, missing content etc.

What Can you do? You can be the leader, pres, or whatever
you want to call it, get it going if you want. or not.

Thanks,
Mike T
