Linking contacts

I need to link two contacts in Zoho CRM. I operate a nonprofit that has Sponsors and Students (3rd world students.)

Is there a way to link these two together? I would like to have all in as contacts and connect when appropriate. Sidenote: some Sponsors have multiple students and will need to link to multiple other contacts.

Thanks for the software! We spend no sponsor money on overhead so love Zoho CRM.

Thanks,

Shawn
