Basically he's looking for beta-testers for his scene-editor/ gameengine-editor that Funbyte makes to work with a free engine (I think the Funbyte team uses the Ogre3D graphics engine).

I've translated a bit;
"
We, the Fun-Byte Media Team is looking for Beta-testers for our leveleditor which is currently under extensive development.
We not only want you for testing, but also for feedback on the design of new features in our programs. We work on a very professional basis, but without the pressure of time (nearing deadlines?).

The Editor is programmed with the Microsoft Foundation Classes (MFC) and C++.

If you're interested in testing, write an email to:
SebastianLeopold@aol.com or contact me through MSN (same address)"

Cheers
