Online portal with user rights to upload documents

[vampiredevil]

Hi All,

Me and my friends are looking for any online portal to share files with each other. Currently we are using dropbox with the same user id but the problem is there are no. options for defining different rights for different users, such as
User 1/2/3 : can only upload
User 5: can delete
User 4 : can upload as well as delete.

Any of you have any idea of some website/software, probably free , which can give us these features? will be of great help for all of us.

Thanks a lot in advance

Donot think that there is free service which is better. For online collaboration with things you want you can try Dropbox Team but that again is paid. What type of files do you exactly want to move around.
