I’ve opted not to charge a fee for using the site’s services (except for adding an ad to the “ads of the month” section) to allow as many people as possible to take advantage of them and also because it’s difficult to set a fee that’s “fair” for everyone. (The budget for advertising is not the same for someone with a small supplementary business, for an association or for a well-established business… )

That’s why I suggest you to make a contribution of the amount you choose, which is fair for you in terms of what the site brings you and what you can afford.
