Here's a quick update that you may find helpful:

I have just added a link to the right side of the site called "Post Category". (You can view the right column on any page except the home page.) It is a drop-down menu that allows you to select a category and view all posts in that category. When you click on the "Select Category" button, you will see every category entered into the site so far and how many posts related to that year have been made on the new portion of the site.

You could, for example, search for your class year, but an even better way to do that is to enter the year in the search box at the top of the right column. That will search not only for all the recent posts but all mentions even in the old site for that class year or term.

I hope you find this helpful!
