can I give access to 6 people each with three difren pages to look after and still have full controle my self?

i curentley run a computer group web page and 6 others have to send me changes they wish to make to the page or thair particular SIG group page or they have to manage thair own individual sites and all i do is place a link to thair sites it dosent give me the control my commitee requires.

if each person had a particular password they could change thair page and it would be all on one site.

Thanks.
