I should know, I did exactly what you are proposing for my mother last mother's day. She wanted a website where she could share her quilting and craft projects with family and friends...

So I setup QuiltZilla for her. I took me five minutes to get it up and running, and it only took her 10 days and a digital camera to get the first 200 pages of content in the system.

But don't take my word for it, check it out for yourself.

Kwiki is a simple wiki based content management system, that even my mother can use, and it only takes minutes to set up.
