i want to weld the upper vertex to the lower one. (see image)
how do i do this?

thanx in advance! 
weld
Alternatively - if you want to move the top vert to the same position as the lower, before making the 2 verts one - use scale (rmb) to a point
Select top vert
Scale Uni -> rmb option
Select lower vert (as destination / target / origin)
Drag 0% (hold shift to constrain)
Select object and cleanup
Will need adv menus enabled

Some more info on scale (to a point) here - if not already seen.

uh… you could also, if you want to veld the top to the bottom vertex, simply select the top on, and press “backspace” to delete it
you then re-connect your edges to the lower vertex,
wings works off a solid object instead of a polygon “surface” so deleting a point cannot create a hole in your mesh
whoah! 3 ways to weld a vert?:eek:
thanks for the help! 
puzzledpaul, thanks for the link!
