I've recently installed ubuntu 10.10 on my Compaq Presario V3000. All was well - I had installed my favorite apps, updated the repos etc. But today, I find that the Messsaging Menu (the one with the envelope icon, which becomes green if you have a new chat/mail notification) is completely missing from my desktop panel ! This is very inconvenient for me, as I can no longer use the integrated Chat menu ! I've attached a screen of the panel as it is now .ie. without the messaging menu icon - can anyone please suggest how to bring it back on ? Thanks
Sounds like it has just been removed form the panel. Right-click the panel -> Add to panel, and filter to find the 'indicator' applet, and add it.
