There are certain facilities and features of this site which will either not be available to you,

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 firstname.lastname@example.org and can
normally expect a response within 24 hours. Please don't just register another account as this creates extra
work for us.
If you can't remember your password, enter your Username or email address in the login form use the password reminder button to
