To my surprise I can not find any extrude mesh option.
It is a offset mesh tool, but no extrude (that I can find)
Please add it! Altering meshes by hand takes too long.

Yes, absolutely! In conjunction with Weaverbird we would have a very nice Sub-D modeler (we just have to teach Rhino or .Weaverbird to remember subdivision levels).
Hi Jorgen- in V6 you will be able to extrude meshes using the gumball (ctrl down style gumball extrude) but so far there is no actual command for this.

Ok, but that’s no help as the installer doesn’t work 
I made a script that works around this, by duplicating the naked edges, extrude into nurbs, then mesh those, then join. But the objects aren’t water tight, even after welding, and that surprises me as the mesh edges are within tolerance.
