Source Code Permissions [ANSWERED]

[the_best_flash]

What do we have permission to do with the source?

If I wanted to take the VB6 source, and rewrite the engine in C++.NET would I have permission to do that?

After programming graphics and networking I would mostly be copy/pasting the non-buggy functions and converting from VB6 to C++. Do I need permission to do this?

Where would I give credit to the original developers? Where can I find the list of developers I need to give credit to? Is it just the list in the credits?

Also can I host the source (As in the C++ code I'll be writing and not the VB6 source) on an open source site, such as Sourceforge.Net (The SVN would be useful).

If and when this version is completed it will, of course, be posted here and given to the community. I have no intentions to release a completed version of this on sourceforge.net, I would only be using it for the SVN capabilities.

Thanks.
