Axis Blender to Ogre

Hi all,

    Im making a game just now in a team of 5 with the Ogre engine but I 
have a problem using blender meshes because when you export objects 
from blender, they sit on their side in the ogre engine. How do I 
change the Axis on blender so thatn 'Y' points up in Blender instead 
of 'Z'? And can I import blender objects into Ogre the right way up 
instead of on their side?



Many thanks,

Martin K.
