Hi Luke,
IFSO has not really been active for a while, I'm afraid. We still have the mailing list, but we haven't physically met for a couple of years. There was a bit of a boost to interest and attendance after a talk Richard Stallman gave in Dublin back in February 2013, but it waned again. Since then, we have taken part, via written submissions, in a couple of public consultations at national and EU levels. Having said all that, a few of us do meet up for a pint or two in Dublin quite often anyway, outside the IFSO umbrella, so give us a shout if you're visiting Dublin, and I would think we could dust off the stuffed gnu and meet up!
Ben.
