How do I go about this:
For a social site I need to allow users to find people they may know on the website.
1) Find friends on our site - Done. 2) Find friends from their email (hotmail, gmail, etc.) 3) Find friends from chat (AIM, ICQ, etc.) 4) Upload CSV files - Done.
For 2 & 3, there is a huge list of email and chat services. I gues it works like this: Users enters id & password, system retrieves the email/screen names from the user's account. Then scans the system for any user with entered screens names in their profile data matching these and returns the results?
Second question is to allow my system to get the info from other services like ICQ, skype, etc.. how to go about that? Does each have their own API to use or can i use something for all of them?
