Guilds created in MB will be wiped along with everything else. As the whole guild structure is different in CB anyway, you\'ll have to re-create it there.
Updates to CB will not require you to rebuild anything. However, any completely new versions that may be built in the future probably will require it.
Not sure what you mean about picking \"other/double name(s) for our character\". But whatever that means, I\'m sure you won\'t have to do it.
