Be sure to check the back issues. It was the place that got me started with dio's and taught me to think out side the box. Also, do seaches on this and other modeling forums for dio's or the thing that you're wanting to do. And be ready to start looking at your trash in a different way. I've gotten so bad, I have my wife bringing me trash to use in my designs.
One more thing, don't be afraid to ask for ideas. These folks are great at giving out their ideas and tricks.
Good Luck
