I’ve setup a very crude archive of the previous Tips and Tricks sections from the GWN, available here [Edit: Wayback Machine has it archived now].
There is a lot of good stuff in there. I remember reading a lot of them myself years back, and that’s where I learned quite a bit from what I know now. Pretty cool stuff. Maybe in the new section I’ll throw a link back to the old ones — they are still as relevant and useful today.
