"Belated" because I keep thinking about these but forgetting to post:
 
First, a big "I second that" to Vanessa's recommendation for www.davesgarden.com .  I so often wind up there, looking for cultural requirements and/or pictures.  I also like many of the forums on GardenWeb.com--plus, members have been quick and helpful when I asked questions.
 
Second, a design for a compost bin at http://www.wikihow.com/Build-a-Cedar-Lattice-Compost-Bin.  Haven't built it yet, but I  already love it for my fave "3 E's": easy, elegant, efficient.
