Basically, this web site allows you to bookmark someone as a crush. If your crush bookmarks you as a crush as well, you will both be notified. Otherwise you will remain anonymous.
The finer details:
After you have provided your name, the database will be searched to see if anyone has expressed their interest in you. You will also supply the details of the people you are interested in. The system will check for reciprocated interest. You will both be notified if there is any reciprocation.
If the people you are interested in have not joined the site yet, they will be sent an anonymous and friendly invitation to join. They will also be asked to provide the names of anyone they have a crush on.
Your name will not be shared with anyone. The people you like will not know that you sent the invitation or that you have a crush on them.
While you remain registered, the system will continually check for reciprocated interest between you and others. When this happens, we will notify both of you with your permission. If no one is currently interested, your crushes will be saved in the data base until you delete them or a match takes place.
