On Plenty of Fish and Match.com, when I selected matches no more than 100 miles away, they showed matches 300 miles away and farther.

"Can't they do math?" I wondered.

Was reading not long ago here, that a Woman drove 4 hours(one way) to meet a member,she went home, things were looking good, but then she and her Mother had a long discussion and the relationship fell apart.

It's for prospective dates. If they see you live in Detroit, for instance, and see that you won't travel more than 100 miles to meet anyone, they will likely cross you off their list.

By the way, this website has a bit of a learning curve for dating.

If you upload a clear photos of yourself, answer the profile questions and write your profile, listing your hobbies and interests, you'll earn website points, and members can get to know you.
Commenting on posts and writing your own earns more points. At level two you can private message people, and at level eight you get an agnostic T-shirt.

The website uses profile algorithms to find member matches, so the more details one includes, the better the match.

Many women prefer to see a written profile talking about interests, hobbies, and backgrounds that can be quickly perused to find compatible partners.

In case you didn't know yet, to find members near you, click on the "Browse" button at the top of the page, then on "Members," and enter your preferred search parameters.
Click on the "Discuss" button, then "Nearby" to find members near you also.
Or click on the "About" button at the top left of the page to find links to FAQ or the website tutorial.
Points are now being given to level 3+ members who chat. You can see chat rooms on the group main page or at [agnostic.com].
