Shoutbox

Before i start i did read the older post on this topic but i couldnt really find a definitive answer to my problem.

My Event Viewer is working 100% except for the fact that a *few* of my contacts are not displayed when the come online / go offline.

My internet connection is 100% stable, and I never drop out.

Could this mean that the contacts that aren't being displayed have deleted me from their list, but not blocked me?

Thanks
