Does it provide the development platform I think it is just a place where you can find the developer by paying money is it related with opensource.
if it is the opensource project you can use
this site provide you project management option too
It is just an announcement board where developers find work and project managers find developers and designers. Most of the time these are paid jobs, but not always.
Here in SitePoint, I would use the marketplace.
I agree. Sitepoint Marketplace is the best place.
