Is there a forum or place where you can request a developer create a particular app?
In the developer forum...but honestly I've not seen but maybe one or two people that actually develop apps post here.
The only one that jumps right out at me as an actual app developer (not some rep from a company and not a ROM developer) is the guy that makes MyLock.
I called a company that makes apps for the Android system and their base charge is right around 1000 dollars. Just to give you an idea of what you are looking at. It's not like "hey make this" "ok no problem give me a minute".
I've already posted asking if such an app is available (simple running log linked to a website so it can be updated on the Droid or the website). There are a million complex apps that log your GPS etc, but I dont want to do that. There was one app that kind of worked but it was too clunky and not really designed for that purpose.
