Free to ask and free to be listed. Paying never gets you in: a listing is decided on its merits first, and placement is only talked about after.
Listings are our own opinion, written by us. Some links are commercial and marked as such — see how we make money. Nothing here is financial advice, and a listing is not a recommendation to use a service.
