We’d like to let you know that starting at 9.00 a.m. GMT on April 17; we’ll be upgrading our forum software.

The update will take about four hours, during which the forum will either be unreachable or will have limited functionality.

Apologies for the noise and dust - what comes out of this is a better forum for us all.

UPDATE: Upgrade for our forum has been completed and all services are working again
