We do not impose any artificial limits on the number of user accounts you can set up
on your account, or how many people can access your newsgroups simultaneously. If you choose,
you can also leave your newsgroups publically accessible and not require a user account to
access them.
However, most of our users do choose to limit access to their newsgroups, and you have
full control over how this is done. You can change what level of access (read, post, reply)
each user has to each newsgroup individually, providing you with the fine level of control
that you need.
