Converting google talk IDs into email addresses?
 

I've had an N900 for a couple of weeks now, and generally love it - However, there is one annoyance I have with the contacts app.

For most of my google talk contacts, their google talk ID is also their email address.

However, I can't find any way to get the address out of the google talk contact entry and into an email contact - short of retyping it.

Am I just missing something obvious? I couldn't find any place in the contacts or conversations tool where I can select and copy the email address.

Any suggestions?
