I have a website developed in codeigniter and need to add two functionalities:
1) blog - (simple read only with the possbility to share to faceboo and tweeter)
2) promotion - on user's subscription page we will place a link to a page that will display all other users the current has invited and signed up. This page will have a form for the user to enter the email address(s) of other users they wish to invite with a short message.
You need to be expert of CodeIgniter and have time to work on this (no time wasters please)
