A Button Tutorial, Great contribution, just needs to be polished.
Tutorials are always welcome, they can even be rough. But this is really rough.
The thing that really irked me, was the constant of 'U' and 'B4'. While they do not detract from the information, they are really unnecessary. Go the extra mile and type 'you' it's two more keystrokes over a space of 4 keys, it's a small step to make to make people take you more seriously. Fix and resubmit for a higher rating. =)
