Hi Sue…
Yes, it can be frustrating when local notice boards are not used… in the smaller hamlets.
However, more often than not, there is a display case outside the Mairie… where such notices will be displayed… what they put in there can make interesting/challenging reading sometimes… 
So for people like me who have not quite retired to our French house does anyone know if we are expected /allowed to be included in the census?
Andy… have you checked with the first Link to see if your Commune is being included this year… ?
we’ve had our already so have allot of the communes down our way. on the ball
