Sunday, Sakon FC 'Open House'

In the past Sakon FC had a pre season gathering to introduce the team lineup.  Was wondering if there was to be one this year and asked: "any team introductions before Sunday?"    The answer I received "Sunday, February 11, open house to welcome the visit of the United Khon Kaen team."   I understand "open house" to mean, no admission charge. The Thai definition may not be the same as mine? Pictures pre game team introduction 2011
