The IFRN e-mail addresses are directed via the Biotechnology and
Biological Research Council in Swindon who fund the Institute. Therefore
all addresses are XX at bbsrc.ac.uk; unfortunately they do not always use
just the surname + initial; however it is worth a try.
One definite e-mail address that I know is that of Catherine Reynolds
who is the external liaison officer at the IFRN;
ifrext.relations at bbsrc.ac.uk
I also attach the IFRN WWW URL.
I hope that this helps.
