User names are usually FirstName.LastName, ie 'John.Smith'. They are not case sensitive, but occassionally include
a middle initial or a number on the rare occassion where we know of two people with the same name. If you can't
remember your user name, then you can also try using your email address. If you are totally stuck, then you
can email email@example.com and can
normally expect a response within 24 hours. Please don't just register another account as this creates extra
work for us.
