Mechanism for Changing Guild Names?

Is there a thought about guild names being permanent or will/is there a mechanism for changing guild names?

I've already seen one guild change leaders, so I'd imagine as guild changes, it might be interested in changing it's name and/or mission statement. Which also reminds me: will there be a place to file Guild charters? Will there be such things or is that just something voluntary for guilds?

If there are guild charters, there should be some place inside the guild hall to view it.
