Last active date in topics

When reading older topics you mays want to ask a poster a question. Then it would be useful if 'last active' was shown under the avatar. (If the user hasn't been active for a year he probably wont read your post..)

I know this can be seen in the profile, but most users don't. I regularly have to tell posters on my forum that their questions to a poster will probably never be answered...

(As far as I can tell 'last active' is not available to the Topic skin)
