We compost using three methods: 1- A regular compost pile in the backyard. We too live in one of those HOA communities who do not permit compost piles because "it smells." Yeah, well, a healthy pile does not smell. Ours is a 4x4 wire system like petlady referred to, and we have it in a corner of our yard hidden by a 6' fence that encloses the entire yard.
2-A vermicompost bin in the guest bathtub. Ours is homemade...just an 18 gallon rubbermaid tub with airholes drilled in the sides and bottom.
3- Trench composting, which Mialsse asked about. It's a slower form of composting, but it works! Simply dig a trench or hole 8" deep, fill with roughly 4" of kitchen scraps, then backfill with soil. As a young kid, I got to help my mom dig the holes into which she deposited organic material. Next Spring, the area was perfect for planting!
Mialsse: Googling "trench composting" will bring up tons of links if you'd like to know more. Happy composting! :)
