I don't know if the bylaws document has been updated since this change, but this is what stuff concerning realm activity and whatnot has been changed to:
viewtopic.php?f=13&t=4043915.2. An active realm in BMCS:
15.2.1. Must have and maintain at least ten (10) active members. An active member is defined as a person who has singed a waiver and either attends practice once a month during the practice season and/or attends three inter-realm events in a calendar year.
15.2.2. Must register with the BMCS. Either contacting an Officer of BMCS, and/or the BMCS online message boards.
15.2.3. Must use the rules for combat based on those contained within the Book of War of the BMCS. A realm may develop realm-specific rules. However, the national rules will be used during any inter-realm event.
15.2.4. Must not be within 20 miles of another BMCS realm. Alternatively, if within 20 miles of another BMCS realm then must have at least ten (10) active members separate from the other realm.
15.2.5. A realm must have a regularly scheduled practice at least once per month.
15.2.6. A realm must have a written constitution and/or bylaws. These will be submitted to the War Council for review prior to being granted speaking or voting status.
