[support] Domains, subdomains on D7

[John Summerfield]

I am trying to create a website for a club, we'll call it's domain 
example.com

example.com should be the administration site, no club members per se, 
although its registered users might be members of associated clubs, its 
in order for that to be the case.


Associated clubs with have subordinate domains, so friends.example.com, 
raiders.example.com and so on.

It's also in order for people to be members of more than one club, and 
they often are.

Example.com will provide some general information that should be 
accessed directly by all the subordinate clubs. On the other hand, each 
club will provide information of its own, and that should be accessible 
in a menu item, "club news."


Also, each club should be able to provide some specific information as 
an alternative to that provided at example.com.

For example, example.com/About would tell its visitors about the base 
organisation. For example,
"We promote our sport....
"We have associated clubs here, there and everywhere."

raiders.example.com/About would say that

"We have these competitions....
"We have school programs at ....
"Our clubrooms are at 45 Raiders Way, Bordertown."

and so on.

What I want is for Raiders visitors see only raiders.example.com/About 
but not the one at example.com or friends.example.com.

What happens is that a user registered for both example.com and 
raiders.example.com has, not one, but two /About links.

An example of information that only Raiders can see is Raiders' 
membership list. Our law requires that membership lists of all 
incorporated bodies (in Australia that means Example Inc, Raiders Inc - 
company names are generally titles Ltd or Pty Ltd) must be available to 
members. For the present I don't propose to provide more than just the 
names of members, but I do wish it to be available only to those 
members, and not to General Public.

Similarly, Club News would mean Raiders' news at Raiders, Friends' news 
at Friends, but their news should be accessible through another menu choice.

I have a working list of associated clubs, so switching between domains 
is trivial. I an happy to have just one list of members, but they must 
only see member's-only content from whichever site they are looking at 
at the moment, and then only if they are members of that club.

I have been trying to do this with the domains modules, but I am not 
sure that the will let me do what I want without cutting code. I am 
pretty feeble with PHP, but I might manage a small amount.

Does anyone have any advice on how to achieve my ends? Is using the 
domains modules my best choice, or should I look at something else?
