granting full access to 3 sites: user/grp settings

[acctman]

i have 3 sites/users that all need to be able to access each other with complete read/write/exec access

Site1 Site2 and Site3

what's the best way to do this without screwing up all the premissions and access to my currently active sites. I need advice from someone who is a pro at this and not just guessing at what premissions to set. I'm assume i need to create a MasterGrp and invite all 3 sites then set/change permissions on all three sites. Also all new files created would need to have the masterGrp set as the group automatically

I've already had to restore twice after receiving bad advice on another forum.

please be clear on what are you trying to mean. and i didn't get the point 3 sites/users. does it mean that there are three site and three users and each users hac complete permission over the sites. not a great idea fromwhat i'munderstading unless you are planning toimplement acl.

i have three sites, site1.com sites2.com and site3.com and i need the group/user to be able to access each other. All 3 sites are apart of each.
