what should the following values be?

[hypersdc]

I'm setting up my chat rooms and I have a field for the following:
Room Owner and Max Users.
What should these values be?
Where do I read more about these?

Also, I noticed the default rooms are not showing up in the admin area. How do I remove them from my chat?

And 1 more.
How do I change the default admin password?

Thanks in advance.
