I went undercover and logged in, to see what it was like and report back to you, readers! To create your profile, you just have to fill out a quick "About You" survey, to help generate your profile. On the professional side, it asks for your degree level, subject studied (arts, humanities, law, engineering, medicine, or sciences), and current profession. On the personal side, it asks for your date of birth, marital status, sexuality, politics, and religion. Next, you use a map to "locate" yourself, zooming in as far as your very street, if you want!
After you enter your own stats, you then have the option to select what you are looking for in a partner -- with the same categories as above. Upload a 140 character statement about yourself, and then a more detailed paragraph, if you want, plus the all-important PHOTO, and then, viola! You're now officially a member of Gradhearts.
Regardless of opinions on grads dating grads, and although I can't say first hand if the site will find you an eternal romance, or even a fun fling, I wanted to let the GSAS world know about it, in case you have a special holiday wish this year. :)
