But where do I get information about where to place things on the web, how to call/reference them, what permissions do my files need, how do I protect pro...
I have the following code: - (void)setItem:(Todo *)newItem { item = newItem; } Why is it that I can't do - (void)setItem:(Todo *)newItem { self.item = newItem; } ?

I'm creating a forum for a website, and plan on implementing a "Report this content" function. In all honesty, I'm not sure how useful (lit. necessary) the feature will be, since a user account (created by admin) will be required for posting, but the solution interests me.
