Need help setting folder permissions

[CN]

I have a shared folder and would like to set permissions
so that members of a group can read, create and modify all
files within that folder but files can only be deleted by
their owner. Any help much appreciated.

That may not be possible, as modify also entails deleting files. Writing also allow
appending data which may or may not accomplish what you want. You could try setting
the general group permissions to read/list/execute/write and creator/owner to same
with modify and test that configuration. Modifying a file often is a delete/create
process. --- Steve
