We have recently started using vitero for training and learning purposes in our strongly growing network of entrepreneurs.
The great thing about vitero is that it is really easy to get familiar with the tool and work with it. All the women (and men!) of our network really appreciate the fact that they can use such a great tool for effective Web based communication 'just like that', meaning that no special knowledge or previous experience with electronic communication over the Web is required when working with vitero.
