Have you heard of Samepage? Samepage is a free service, that allows multiple users to manage projects, share content and conversation all on one online page.
Sampepage is great for groups large or small and helps keep any group organized and informed.
I love that you can share to with friends on social media, like Facebook. It's very easy to learn how to use this site. You can share files, maps, photos and even videos, to other social media networks!
Also Sampepage has an app for Android and IPhone users. I use it mostly from my Samsung S4, I haven't experienced any crashes, bugs or issues with the app.
