Hi Adam,
Good plan. I have created many town projects. Make sure you have your exact title of the prospective project written out on paper ahead of time. Once you create the title you can not change it easily. Follow the hundreds of other Jewish Town Projects format for your title. Your example shown to the left here is too long for searches and links. It's a Title, not the entire encyclopedia and history.
Links can be added later. Easy to do in the right hand side of your new project.
I think your "main purpose" is too limiting. Make it a real town project with proper short description and text encouragement to users adding profiles, not just a "photo" collection.
My thoughts.....
Dan
