as it isn't designed for multi-user access. You would need at least reseller account or root access to create individual accounts with separate access.
In terms of cost, for around $5/mo you can get your own account, which is pretty low cost. Sometimes when you need certain functionality, you have to get the product that meets those needs.

If a domain has several subdomains, is it possible to have separate passwords for each sub? I am revamping a genealogy website; I totally recreated a test site on one of my subdomains. I wanted to transfer it to the original site to revamp it. It is hosted on someone's account at Bluehost. The user name and password are for FTP access to the account and the family has their e-mail hosted there. Is there any way to leave everything there "as is" but enable others just to access the genealogy site to keep it updated? The original intent, I believe, in setting up the site that way was to keep cost down. The genealogy group would like it to remain a .org website not change to .com. Thank you.
