Ok here is my situation.
I am creating a blog whose purpose is for its community to also be able to post in their own "private area" of sorts WITHIN the blog.
User 1 registers an account on the blog/site.
User 2 registers an account on the blog/site.
User 1 decides to write a post about his day...
User 2 wishes to read User1's post, so he selects/clicks into User1's "private" section (which ONLY User1 can post NEW topics in)
User2 reads User1's post, and then proceeds to comment on it, creating discussion in User1's "private area"... etc.etc.
How would I go about implementing this type of infrastructure? I havent seen any solutions jump out at me sofar.
