On the invite-only site, only you, your friends and people connected to you by fewer than three degrees are visible.
When you’re browsing profiles, you can see how you’re connected to each person, and your friends can make match suggestions for you.
Upside: A personal reference for every potential date.
Downside: Your common friends will inevitably hear feedback about your dates.
If you're a man, you need to be a verified graduate of a school on the site's list of "top universities." Payment also works a bit differently than traditional dating sites. Men pay a small fee to start conversations, which theoretically prevents them from spamming everyone on the site.
Upside: Men have to invest each time they communicate and are less likely to do so when they aren't sincerely interested.
Browsing the site is free, but unlimited messaging costs $20 per month.
