LsFarm suggested this which is good idea. I've added custom fields in the profiles to add the make and model of the Coal stove/furnace you are using. These will show up in the pane to left of your posts. These are also available on the registration as of now so I'll just leave this stickied for while until people who have already registered know about it.
You can add this by clicking the User control panel link, then click the profile tab.
