convert dae md2


I have blender 2.57 and I want to convert obj files to dae or md2 format because my 3D rendering work wont use obj files well.

When I load a obj file do I just export the file to dae and that is all you do? I read there was also a plugin for collada so i dont know if i need this as well because collada is an export option already.

I dont see an md2 export option.
