Black Hole

Only a minor niggle, I know, but the means we have to find what we're looking for in Conversations is primitive compared with forum threads. A means to skip to last message instead of having to open the conversation thread, click the last page number, and then scroll to the end (for example) would be nice (doing the same for a forum thread is simply a case of clicking the last post date in its index entry).
