Who you want to contact at RAWSOC depends on why you are contacting us. Usually you'll want to contact someone on the Exec, but here are some pointers:
For most general enquiries you should contact the current President. This includes if you wish to join RAWSOC or just join us in the pub, coordinating an event with us, seeking more information about anything, etc. Rule of thumb: when in doubt about who you should contact it's probably best to contact the society president and he or she will forward your enquiry on to whoever should best deal with it.
For access to our library you should contact the librarian.
For anything relating to the website (e.g. you find an error or wish to query something) or forums (e.g. you need help joining the forums) you should contact the webmonkey.
