How can one join the Royal Society of Chemistry as an AMRSC (or MRSC) without a referee? The Royal Society of Chemistry (RSC) is an amalgam of what used to be many different societies, and has a long and rich history going back to Faraday (who incidentally, never received any degree), and it is considered a learned society, like the ACS in the USA, of which I am a long-standing member.

I have perused the RSC website extensively and I possess the necessary education and experience to join as a Associate Member, but one of the requisites when completing the application is that I name a referee, optimally someone who is already a member.  

I do not know anyone who is a member as I live in the U.S.A. and simply have not crossed paths with such a person who would know me well enough.  I am aware there are offices in the US (Philadelphia) and there is not categorical statement that you must be of a certain nationality, so how do "Americans" apply?  

Does anyone know how this process works?
From the help page of the Royal Society of Chemistry: 


  Who can be a referee for my membership application?
  
  Preferably a member of the Royal Society of Chemistry, however if you
  do not know a member who can act as referee, a member of a similar
  professional body can provide a reference. In some cases, a reference
  from a senior colleague, for example, your line manager or head of
  department will be acceptable.
