Finding multi users online status

[es_amini]

I want to know yahoo users online status.
I want a method that checks multi user at once.
Current solution for me is taht I check this users one after one but this is time consuming solution.

I want a method like this:
http://opi.yahoo.com/online?u=user1,...,user4,...&m=a

I suggest going over to www.onlinestatus.org and having a look at there implementations. Perhaps a way of using there system might help you create this method. Also try asking a few questions in their OSI Forums.
