Guild assemblies are the F-guild's highest authority, where the members decide on the direction of the guild. There's at least one general meeting each term, named the Autumn/Spring guild assembly. Matters such as motions and electing volunteers are settled at these. At times where either an unforeseen issue has arisen or a group of at least 15 members has requested it of the board, one might call an Extraordinary guild assembly to settle the situation at hand.
Here's the meeting documents and minutes concerning the guild assemblies from the last few years (in swedish). If you'd like to access older documents and/or minutes, contact the board.
