I have 2 questions. In google talk it is possible to "link" a contact to an address book entry. When I go to one of these entries in my address book I want to be able to click on the google talk email (gmail address) and then email them. However, the address book does not give you this option, just the option to IM them using google talk. Is there a setting I need to change to do this?

Also, has anyone heard of a facebook chat client? I haven't even heard of one for desktops, but I was just curious...
