Maybe 4 hours to make the special-purpose tool, done in a way that makes sense.  (We have some more things to discuss on this.)  Probably 1 hour to make the error monitor report it, then an hour to get all parts of it into place.  Add padding as appropriate.

So, actually, all of the mailin machinery would be exercised but you wouldn't end up with an enormous number of blog entries stored unnecessarily in your database.  If we're sending a tracer email every 5 minutes, that's 288 blog posts a day.  After just a week, your test community has 2016 blog posts in it, and growing.
