I'm a member of a small (~15-20 people) club that needs to store some documents for all the members to share and access. Everyone, or at least many people, should have write privileges (and yes it will be backed up regularly in case of accidents). The documents don't need to be large - total storage of <100MB should be fine.
At first we thought about Dropbox but the free version of Dropbox only allows 1 account per PC user-login, i.e., if I already have a personal Dropbox account I can't also use the club one. Can anyone suggest some good alternatives? Thanks in advance.
