Ability for users to post memories for memorial website?

Hi all,

I'm a newcomer to Squarespace but have decent tech literacy.  I'm putting together a pretty simple memorial website for my mom, who passed away recently.  I'd like to have a page where her friends can leave memories via some sort of comments function. But I don't like the blog solution (i.e. do a blog page, post a blog, and then have folks comment on the blog).  Ideally they'd click on the page and see a simple interface where others have left memories and where they can easily leave their own.

Any suggestions?  This is the only remaining challenge, I've figured out everything else I want to do (my main goal is to share photos).  Also, I'm not up for adventurous programming at this point, really just want to get something up for her friends quickly, and I'm myself also in mourning.

Many thanks in advance, Annette

Were you able to figure this out? My Brother in law is trying to do this for his father?
