Community links are sites that serve primarily as news or gathering places for the online painting community. Sites here will usually have forums, tutorials, and updates from our little miniature world.
Painters links are sites of individual painters. Or collectors of figures painted by painters. I'm not picky (just lazy).
Commercial links are people who are trying to sell you miniatures or miniature related parephenalia. Only those businesses that I have personally dealt with and are otherwise reputable are listed here. Unless of course, they've paid me a nice placement fee.
