The Menu Bar Icon one is the easiest.
Go to Messages > Preferences > General Section
Tick the top box (Show Status In Menu Bar)
DO you mean you can Screen Share over Bonjour or Jabber (GoogleTalk) ?
Can you Audio Only or Video Chat over an AIM Buddy list ?
Screen Sharing is actually an Audio Chat+
The Bit rate needed (Internet Speed) is about 3 times the normal Audio needs though.
This brings it in to line with a 1-1 Video chat at minimum speeds (Around 128kbps)
I would speed test your service
http://www.speedtest.net/You need to have that Speed as Upload as well as download (Mbps are faster still)
0.7Mbps is roughly around 700kbps (that is using base 10 where as the maths is actually based on multiples of 2)
You also need to check the Video Menu in Messages to ensure Screen Sharing is Enabled.
If it is and it is greyed out it wll be about speed.
Check the Connection Doctor (Video Menu) and the Capabilities tab.
Starting up Messages at teh same time as the computer may cause Messages to record the wrong Internet Speed.The Speed test should be done when the computer is not doing anything elese such as a download.
Other computers, Games Consoles and even Mobile Phones can influence how much speed the computer then has (Then called Bandwidth if the connection is shared)
