Exchange 2007 not displaying Send connectors

Exchange 2007 Send connectors not displayed
Just set up my first exchange server
Exchange 2007 on Windows server 2008

However I need to amend the send connector, but the send connectors are not displayed in the Hub transport role.

Initially I had to set the send connector in the Shell. Now i have to amend it as it seems we cannot send to some domains including AOL

So my query is two fold

1) How to I get exchange to display send connectors

2) How do I amend the send connector to allow acceptance in AOL and some other domains

many thanks
