Creating a basic Classmates.com profile is free. To build a profile, you simply visit the site and identify the school you attended. For users in the United States, this process begins with the visitor selecting the appropriate state, city and school. This leads the visitor to a membership form.
To join Classmates.com, you must provide your name, date of graduation, birthday and e-mail address. You also must create a password for your account. Once you've filled out that information, you'll be prompted to purchase a membership package. Packages range in price and duration -- the longer the term of membership, the lower the price.
If you don't want to purchase a membership, you can continue to use the site with a free profile. The site will lead you through a profile-building process. This includes uploading a profile photo, filling out a short description of what you've been up to since graduation and inviting other people to join the network. After that, visitors will have the option to enroll in MyPoints, a site that lets users trade accumulated points for products.
Once all that's done, you can fill out your profile with more information about who you were in school, what you do now and the things you like to do. You can also look to see who else from your school is on the service or take quizzes for fun.
Of course, the main reason to use Classmates.com is to reconnect with old classmates. The site features a search engine that lets you view other people who went to the same school you attended. You can restrict searches to the year you graduated if you wish, and you can view other profiles, too. But unless you upgrade to a Gold membership you may not get much farther than that.
