"Image coming soon" Thumbsots.com does not have a preview for that site yet, but they will in time.

This software does not automate reciprocal link checking but in the admin panel, you can use the link check button to check approximately 6 sites in a few seconds. Its then up to you to click delete on a site that doesn't link back.

Not everyone requires a link back, or some make exceptions.. I might list Google.com as a good resource.. but they don't link back to me The software can't make those type of judgments.
