SYKVYH is an abbreviation for 'Suomalaisen YhteisKoulun VanhempainYhdistyksen Hallitus', an approximate equivalent of a PTA Board for our school in Helsinki, Finland (official pages at www.syk.fi). Some email clients out there have very stringent rules for recipient count and so forth. Our volume is 30-50 emails per year, the content consisting mostly of minutes, plans for future activities and such. A commercial alternative in Finland costs about $150 per annum, which I think is a bit expensive for a few emails. If this experiment proves successful, we'll consider using this service (another account) to deliver our news for the classroom parent groups.
