How do I add a classmate that didn't actually graduate with us but went to school for years so he can look around?

Just add them as a guest member. To do this, Manage Classmates, Enter/Edit Classmates, Add New Member, then on the DETAILS page, look for this

Show On Class List:     Yes No Show as Guest Member

Then check the "Show as Guest Member" then they will appear at the bottom of the list in a Guest Member section.

We have an All-Years site and several private class year sites. We put this opening statement on our sites:

This is a private and permanent site for all South Pasadena Junior High & High School students who graduated in 1972, or not quite,
finished at another school &/or moved away.
You are all welcome here!

Take a look at both. Here is the private site:

We don't put them in as guests but you can do that. The one's we put in that are guests are parents of deceased classmates or those that were there for elementary, had a lot of friends but left before junior high (middle school) or high school.

It's up to you. We have a lot of members that left in 10th or 11th grade by no fault of their own. Their parents had to move for work or whatever. This is where their friends are.
