There are already many forks of Luabind. Just look at the web of forks 
over on Github: https://github.com/luabind/luabind/network. take_cheese 
seems to be the one who's doing the most work on Luabind.

You don't have to "request" that you fork Luabind; you just do it. The 
problem is that, with all of these forks and such, there's no notion of 
a true, *official* version. There's nothing anyone is willing to stand 
behind, to test and verify as being a "version" of the app, or anything 
of the kind. There's just random source code on the net.

We don't need new hosting. What we need is for the owner to give the 
*current* SourceForge hosting to the community so that we can start 
making real distributions again.

Virtualization & Cloud Management Using Capacity Planning
Cloud computing makes use of virtualization - but cloud computing 
also focuses on allowing computing to be delivered as a service.
