how do you use an easytoon movie as your signature? what file do i save it as? bmp, gif, wat?

.gif

Upload it, copy the direct link, put it between tags. Done.

You can also do the same with flash.
Properties > export> gif tab and make sure to select 'animated.'

Also, you have to make sure to break apart all graphics, movieclips and symbols.

And all texts, I believe.
