Messages:  I know the website is confusing to navigate, but you can see almost all the comments people are making by checking the "What's New" page.  And comments you make on that page or photos you enter will be seen by everyone -- they're not attached to a particular person (except maybe you).

Photos:  I think it's possible for anyone and everyone to load photos on the Photo Memories page -- go to the Reunion folder and click on the "add photos" at the bottom.  Then select yours from your phone or computer and add a caption. If you need help, put them on Facebook, let me know, and I'll copy them onto the website (that's what I did with yours, Neil -- sorry to be a FB thief) -- or email them to me at laurie.b.ross@gmail.com 

Videos:  You can load videos, but they have to be put on YouTube or Vimeo first, then link to the URL they give you 

Personal information: If you want to contact someone personally and get their street address, etc, just go to their profile and send an email. All other info is kept private by default setting on the website - we can't change it.
