1.) Merging with another guild the R5 of the guild merging into another should have access to a merge/transfer button which will flip all tiles and members over to the other guild. This would have to be approved by the R5 of the new guild to accept another guild merging into the guild. Once they merged into the new guild they will be R1s until ranks have been changed. Then the old guild would automatically be disbanded so there are not a lot of inactive guilds hanging around.
