There are some very old articles on Blender in the Wiki, and personally, I think it might be best to delete them and do a rewrite. Is this all right, or should they be deprecated somehow? I'm not going to do it right now. It currently looks like Jerrot's script is the only way to get geometry into WM, but I don't think it would be all that hard to update the script to the newest version, hopefully. Otherwise, I could just save a floor in the old version, do a save, and upload in a newer version.
