Yeah for those topics which I do end up closing it is normally a 
carefully worded witicism.  Probably one that only I find amusing, but 
still.

My comment on the text for the Codex (as I noted on your talk page) was 
that aged posts can become so quite quickly.  I reckon it's more like 6 
months than 3 years.
