I use rvsitebuilder on the reseller package on my host server. I have new site to set up for a client that likes some of the templates in rvsitebuilder. But, she wants to have access by 4 people to be able to change the info on the different pages at irregular times. She needs a basic CMS so that her friends cannot touch the main body of the site. Is it possible to set rvsitebuilder up to do this without them having to go through the host server cpanel? Thanks

No. All users need to access to the cPanel account.
