any help appreciated
Like was mentioned, merging vertices is what you're wanting. You would select one of the two vertices that you want to merge, select your move tool, hold "V", and drag the vert until it is on the vert you want it to be on. After you have all of your vertices where you want them, go into object mode, select the objects and under the Polygon menu, select the button for "merging verticies". It's a great technique that you can use for organic modelling (i.e. people animals etc.), and once you've merged verts, you can use the sculpt geometry tool to get some amazing effects.
Expect to excell...
