3 bonding sites.

One bonding site that I know of is cbssports.com fantasy football league. This would be considered a bonding site because it's a group of guys that get together through a website and play against each other with the people they picked to be on their fantasy football team. While the games play many sit on the computers to watch their scores differentiate.

Another bonding site would be craigslist.com. It is a site for people to put stuff online to either sell or give away. You can post adds if you have your own business company and you can even find dates or people to engage with. There are a bunch of categories to choose from like housing, jobs, or services and plenty more.

This is a religion site that could be considered a bonding site. They explain about the people of the Methodist Church, explain about their believes, church and society, and much more.
