Nice, thanks for the tip! I'll see that one also! For now, putfile came back to normal and I already uploaded my file there.
I did the tail moving. How's the secondary motion, huh? Followed Tyson's tutorial. =) I'm just having trouble linking the spheres to the bones. I don't really know how to work with bones. I just know I have to add the Skin modifier and then selected the respective bone. But this did not work.
The link is:

The original size is 640x480.
Let me know what you think!
