petrolheads vs pistonheads

[MEMSDesign]

I'm confused. There seems to be different content at www.pistonheads.com to www.petrolheads.co.uk. The latter was last updated 7th December (vs 6th December for the former). Have I missed something?

PistonHeads.com or .co.uk should be used really.

In due course Petrolheads.co.uk will revert to the same content as petrolheads.com
