Convection ovens

I finally got a convection oven in the not-too-distant-past. Joe really just wanted a toaster, but I've wanted one of these bad boys for quite a while. So when we went shopping for a new toaster, I pointed out various convection ovens and we got one of them instead, for pretty close to the same price.

So far, I'm really enjoying it. We've used it to bake breakfast foods twice and just a handful of cookies (from a tub of cookie dough we got recently) multiple times. We're still getting used to it, but we love how quickly it preheats. And it cooks things faster too, which is nice.

I'm still finding that I'm having difficulty figuring out how to adjust the temperatures (if at all) and the recommended cooking/baking time on products, as well as trying to figure out which position to have the rack in. I haven't started doing searches for pages or blogs where people talk about their love for their convection ovens, but I'm just about there.

Instead, I thought I'd ask if any of you have ever used one and if you have any expertise to share with me. So, can anyone reading this help me out?
