I was just wondering if anyone could explain to me how websites likes Facebook create editable user profiles, what scripting language are they likely to use (I assume php combined with MySQL)? Is it creating using forms?
Also i was wondering how the features on the profile work, for example adding friends, the wall etc?
I appreciate that this is a fairly large question but I am attempting to create a similar style social network and don't really know where to start.
Thank you for any help you can provide,
Tom
