and it is a godsend.
Since this forum is the leader of it's category(i guess anyway), and probably an early stop for many beginners, I thought it might be a good idea to keep a link here to this tutorial for the the next bananafiend. It's a really effective piece of work, and I think it deserves more exposure.
Anyway, it's just a suggestion.
