Kerika lets you share your ideas, documents and projects with friends and colleagues around the world using Graphical Wikis:
a unique approach to team collaboration that makes it easy for everyone to understand what your project is all about.
Attach notes to documents and other items on shared pages.
Share large files that you can't send by email, and whenever a shared document gets modified, let Kerika take
care of all the filing for everyone on the project.
And for greater privacy, create your own private network at no extra charge.
