Hi I am the head of two open source projects. The first is about
building an open source computer game. The project is doing quite
well. We are 5 people working and have a good infrastructure in place
to handle our work. We knew each other before this got off the ground
and would now like to expand our circle by adding more volunteer
developers. We only have early releases at this point, so we do not
have a very flashy showcase. How would we go about attracting new
people?

We know that Sourceforge offers a help wanted page, but we are not
hosted there.  Are there good alternatives to this?

I am guessing this is a volunteer project, that is unpaid.  If this is
correct, try posting this on such general public use forums as
www.justlinux.com under software or random/dev. Ditto for other
general use forums, though justlinux is a very busy page with every
level of talent and ambition.  desktoplinux doesnt´seem to attract the
same wide range of people.
