Limited-Rights Subdomains

That's what I'm calling it.  I would like to give my friends subdomains of my website.  The format I want to do something in is basically a 2x4 table.

I have no idea where to start with giving them access and the ability to edit their own page.  I want to limit their editing abilities to inside the table, then limit the amount/ type of information they can post in each cell.

I've just been using Frontpage, which probably means I don't have the skills or resources to do something like this.  And I know it makes me sound like a bad friend - "you can have a page, but you can only post like six words on it" - but it's a certain format I want to stick with.

If you don't have direct help for this, maybe someone would know of a supreme help resource with all the answers to everything ever.

Thanks, but also sorry for a bad question.

There are hosting companies that offer reseller accounts. With one of these you can create accounts and grant access to each of your associates. From there it's only a matter of customizing the system so they can only do what you want them to.
