Hi all,
I support the cloud repository for all the files, dropbox for example, but not something where everybody has editing rights since more often than not, there will be some smart ass trying to screw things.
For me, there should be a team of 3 or 4 persons which are the responsible for keeping everything nice and clean and only they can change the repository.
Europe>Portugal>Lisbon, here.
With Google Docs you can limit who can edit. For example, the docs about the team wallet can only be edited by me. They are set up like that since only I have access to the wallet.
