Yaptime - private groups

"Like you, I have different groups of people in my life – my family, college and high school friends, neighbors, my kids’ soccer team, and other groups that I’m involved with. These are the people that matter to me and that I want to stay connected to, but the conversations are different depending on the group.

I started YapTime because even with all the social networking options out there, I still found it difficult to find a private gathering place for my different groups of friends and family to share and organize photos and videos, plan events using group calendars, and have meaningful conversations.
