There's a 'Private Message' link right under the 'contact' header on the right; your lj email is under it. So, you have it, you just don't know it. :-)

Maybe you should check out someone else's profile for the "real" view - apparently, now users see their own profiles differently than others. Though why *I* would want to see the list of comms I have posting access to and no one else is allowed to is beyond me... @.@
