This study is testing if an educational website called **Current Together After Cancer (CTAC)** helps people who have had colorectal cancer surgery get the right follow-up care. **Colorectal cancer** is a type of cancer that happens in the colon or rectum. After surgery, it's important to have regular check-ups, called **surveillance care**, to catch any return of cancer. But many people don't get these check-ups because they don't know why they are important. The CTAC website aims to educate patients about the importance of these follow-ups and help them manage their care better with the support of someone close to them, like a family member or friend. The study will compare patients using the CTAC website to those using a general health education website over 16 months.

• The study lasts for 16 months and involves using a website.
• Participants need a supporter to go through the website with them.
• Participants must be over 18 and able to read English or Spanish.
