I got the same email as Robbie yesterday. I didn't have any problem going direct to the VM best bits site, what a useless exercise IMHO. I did however then try to log in to My VM and it didn't recognise me despite using an automatic log in that had worked only a few minute earlier on the Best Bits site.
Tried again this morning and got in without a hitch.
If you are still having problems to-day you could try the
VM Community site.
