I understand how you feel about the website. Yes, students just use Facebook.
I've not exactly been encouraged to spend hours on it, especially seeing as every year there's supposed to be a student for that, but I've been maintaining it.
I left the trip reports page up because although it hasn't been updated it still serves as a good example of what ACC do. And it might even encourage someone to give me an update.
I keep the site backed up so could change it entirely. But I'd rather not without input from the students and Henry has the server.
Good news though, there is a 2015 reunion page, it went up when I got the report from Dave:
