"Anyway, I'm none too sure why there should be ?"

To engage with the membership outside of London when the society's activity seems increasingly London-focused?

To acknowledge and celebrate the rich seam of activity currently happening in Sheffield?

To encourage the maximum possible attendance at the first meeting to take place outside of London in several years, by making it an attractive and fun experience?

Just a couple of ideas - not that it's actually any of my business, as I am no longer a member.
