If you want to "save a place" to quickly find it later or mark the "been here button" to keep track of your travel, these two buttons on the place/event pages will come in handy.

Save and I've been there buttons

All the places/events you saved or marked as "been here" are stored and easily accessible from your "My Favorites" section into your personal profile.
