Fleep keeps "old school" participants in discussion via the email integration.Cons:
It has everything that is needed. What makes it clearly the best possible solution and my favourite is the fact that in almost every project group there is one or two "luddites" that are almost impossible to persuade to make an account in a new application. Fleep keeps them connected via their emails. By time they often make accounts and join the others.Timo Haukilahti has used this product for one year.
