Bot functionality, currently active
Posts a notification for original posters (OP) at the Teahouse when their thread gets archived. The majority of Teahouse posters are new users, thus unlikely to know the ins and outs of our archival system, and therefore are liable to repost the same question, assume it was deleted, etc. That bot locates where the thread went and posts a notice to the OP's userpage.

See here for the original discussion and description of that bot.
