[eluser]Pet[/eluser]
hi. you are making a social network site as you say. Im on the same project atm. And is studying the whole website and functionalities which quite advance for my level. Anyway you can peek at this website http://www.kitiwit.com . If you want to create a social network site it requires a lot of planning and module creation as codeigniter is suitable in this task. Start by making a template library that can handle all your page request then incorporate it using javascript, in my case jquery as it is much suitable for ajax call and quite nifty.As for loader i recomend use the set_output functionality of ci and fetch it using $.get() of jquery.
