What Company Is Offering:
2collab is a social bookmarking site where you can store and organize your favorite internet resources – such as blogs, websites, research articles, and more. Then, in private or public groups you can decide to share your bookmarks with others – stimulating debate and discussion. Members of groups can evaluate these resources (by rating bookmarks, tagging and adding comments), or add their own bookmarks. You can browse public groups and bookmarks, but must register (your name and email address) to access the full functionality – such as creating groups, adding comments, and adding bookmarks.
How It Works:
You can start using 2collab now, just register to start adding bookmarks, creating groups and much more – or you browse the site as a guest user.

In addition to the create bookmark form they also provide an easy to use 2collab browser button to add a bookmark from anywhere on the web with the touch of a button.
