CTSD's Practice of Publishing E-mails
To provide some degree of privacy from Spam mailings, especially from those who scour websites hoping to automatically extract ('harvest') lists with the usual @ symbol (and its underlying hidden code), we do not normally display  addresses in such a conventional form.  Instead, we ask you to form the address manually by replacing the given + with the@ symbol..
For example if we displayed info
+ctsd.org.uk
it would be our code for info@ctsd.org.uk
