I want DarkStar to teach me how to model in Blender, but I think when I ask him questions it irritates him :(
It doesn't irritate me its just that there's so many tuts that will teach you thesame thing I would teach you.
Use tab to get into edit mode, then all you basically need to create simple models are the keys b,r,s,e and g.
b - select tool, drag over the vertecies/faces/edges you need.
r - rotate whatever you have selected.
s- scale
e- extrude, select a face and hit this key, then press region. You'll see for yourself, hard to explain it.
g- move
after you hit those keys you can hit either y,x or z to scale on just that axis.
Practice doing this, just extruding faces, rotating them, extruding again and so on.
You'll eventually memorize it all and find ways to make whats in your head.
Also, some useful menus are:
W, Ctrl F, Ctrl V and Ctrl E. Thats not all of them but its the ones I use the most.
And if you're making something for blockland, doesn't scale in object mode because it messes up the lighting.
