My question is why are the Administration modules (File Manager, User Accounts, and Newsletter) not part of the standard module list. It seems to make since with the proper role bases permissions (enabling certain features, like editing or private information) that these modules would be an useful addition to all users; in certain conditions.

I find that that I am frequently paying for third party modules (which have upgrade cots about every few months) that have these modules functionality.

I assume there is no easy way to make them easily available to users other then administrators; without rewriting them.
