Does anybody have customers that go subdomain crazy? as far as im concerned subdomains are useless unless you want to give free hosting to a friend.

I have one site that has 26 sub-domains.
They use them to organize their site easier, e.g. help.theredomain.com, members.theredomain.com, anothertopic.theredomain.com etc.
They are just aliases to directory’s in there space.
If they want to give away free hosting its fine with me (can’t sell it though) they just have to dish out the extra cash when they need more space and bandwidth :D
