I'm looking for a good guide to logging in to a web site's database? For instance, if www.macrumors.com (not using macrumors, just an example) has a log in set up, and in my application I would like to have user's log in with existing accounts from that site (and then later access some info from that site), how would I tackle this. I have the log in objects, fields, etc. set up easily, but just don't know how to interact with a web site's database. I REALLY would love anyone who can help me/point me in the right direction with a tutorial or something. Thanks
