IMPORTANT NOTE 2

In order to be a volunteer at FLoC, you must have the right to work in the UK and we will need to verify your right to work in advance of your first day or on the first day. Right to work would be proven by holding a valid EEA/UK passport (please see www.gov.uk for details) or a valid visa enabling you to undertake this type of voluntary work. If you have any questions about right to work, please contact FLOCRTW@cs.ox.ac.uk.

This is one of the most unreadable disclaimers I have seen, and I think the natural reaction for anyone is to assume that means you cannot participate if you are not an UK citizen. (I had to google what EEA is, and it turns out that it means that in particular EU citizens are also allowed? It would be important to clarify this.). It is also a bit disappointing, given that student-volunteer programmes run by ACM SIGPLAN have had no such requirement (including for ICFP in Oxford last year), and that it makes it significantly more difficult for students outside the EU to apply.

FLOC 2018 VOLUNTEER PROGRAMME ANNOUNCEMENT

Applications to the FLOC 2018 Volunteer Programme are now open.

FLoC (Federated Logic Conference), which brings together several
international conferences related to mathematical logic and computer
science, will be held in Oxford, UK, from the 6th to the 19th of July,
2018. The FLoC volunteer programme allows students and postdocs to
have free participation (no registration fee) at FLoC conferences and
workshops. Volunteers will be able to interact with speakers and
participants, network with other researchers and meet graduate
students from all over the world.

FLoC volunteers will contribute to the smooth running of the
conference by performing tasks such as helping at the registration
desk, assisting with the audio-visual equipment across the different
venues, giving directions to venues, providing information to
conference/workshop participants, general assistance to keep the
conference running smoothly, or engaging with social media about FLoC.

More information can be found at: http://www.floc2018.org/volunteer/

The deadline for applications is 18 May 2018 and applicants will be
informed of decisions by 1 June 2018.

Please note that FLoC also offers a travel stipend programme, which
cannot be combined with the FLoC volunteer programme, see the above
link.

We hope to see you in Oxford!
