How do I share a folder so the members can add but not delete files/folders?

[HRB]

I need a folder that can be shared with my team. 

I need one original folder that keeps the updates with the members but I don't want them to be able to delete original documents..?! Is this possible?

I have tried with sharing the folder .. either we both have the same authority over the documents, or they can not add anything.. 
The other choice was copying the folder into the teamfolder - though now it is not updating the original folder with the info from members...!! HELP please

That's not possible. The only permissions to a shared folder are full edit, or view-only. You cannot create a shared folder that allows uploads (basically, modify rights) without also allowing edit and delete capabilities.

For uploads only, you can create a File Request. They will be able to upload files to your account, but will not be able to see them once uploaded (so they can't delete them either).

This would be a great feature. I see no reason why dropbox wouldn't implement this.
