How can I automatically set my status to Available when I log in?

This is the first thing I do after logging in:

How can I make it happen automatically?

To make the default Ubuntu IM application Empathy start automatically when you log in, the following instructions are from OMG Ubuntu:

Empathy requires a little bit of a kick to get going on login.

You would be forgiven for thinking that checking the ‘Automatically connect on start-up’ box in Empathy’s preferences pertained to starting on system login. It doesn’t, the start-up in this case refers to Empathy’s start up – not your computer’s.

We can make it start on login by going to System > preferences > startup applications > new item and entering the following information in the relevant fields:

Name: Empathy

Command: empathy -h

this script will automatically set status to "unavailable" when screen is locked or screensaver is activated, and will bring it back to available (online) when screensaver is closed!
