exporting mesh+armature

i made a human mesh and linked it to its armature . how can i import it in a scene?

With the file open you want the objects in. use top menus. File > append

Browse to the blender file where the armature is and go to the sub directory named object. Here you will find the armature. Use mouse button 3 to select it and any other object that is related to it. if your not sure just hit A to select all objects then hit open.
