Make sure you save the model. One of the cool things about Lightwave used in Travis' original tut is the subpatch mode. Wings isn't quite so flashy, well what do you expect, it is free! There is a poor mans version of this feature (well sort of) and we'll have a look at that now. CAUTION save before you do this and don't save the next stage unless it's under a new name. We're going to smooth the model and if you save over your low poly version it'll be a nightmare to work on. Right, you've saved haven't you? Good. Press b and click on the model. Now press s. Now press s again. Now press tab. Not as slick as lightwave but not bad!
