Yeah, I have Gmail - now what?

Thanks to Matt Hawley who picked my name from the Channel 9 GMail request list I now have a Gmail Inbox. And I'm now thinking - now what? I'm 'currently using 0 MB (0%) of [my] 1000 MB' so search isn't too useful yet. I had hoped that I'd be able to read my other mail through this account, but so far that doesn't look possible - unless I forward each account I guess. But feel free to email me at austegard@REMOVETHIS.gmail.com.
