How to show user presence in MOSS

I've been asked to display the presence of some users in a site. I'm trying to find out what I have to do to do that, but can find no documentation. Has anyone tried this

I have discovered that there is the 'Colleague Tracker' web part in My Sites, which seems to do this - but it's not available on a conventional site. I was also trying to use the 'Site users' web part - but it doesn't seem to be able to show presence (although I've read some comments which suggest it should be.

1) Does anyone know of any documentation

2) What are the prerequisites for showing presence

3) What web part should I use Do I have to make the Colleague tracker web part available on a team site

this is the wrong forum for the question since it does not involve code or custom development.

to answer your question - the presenance information is relying on either Messanger or live communication server (LCS). different web parts may implement the code that shows the current status of the person in the messaging software.

The descision of which web part to use is up to you - depending on the need you have - who do you want to display. Every sharepoint list can have columns of type person that supports showing the online status of the person chosen. so you dont have to use colleague tracker - you can use any sharepoint list.

My apologies; I didn't actually know that this didn't need custom code. I was beginning to think that I would have to write this myself.
