I guess I'll throw my 2 cents in, I haven't said much on OWF.
Ignoring anything that occurred before the coup, and going on what [url=http://cybernations.wikia.com/wiki/Charter_of_Ragnarok]this[/url] says (and it's probably outdated, but it's all I've got at this moment), there is nothing forbidding the RoK membership from overthrowing the Emperor.
Joe and Bob have a logical claim as leaders of RoK if you assume RoK is a monarchy or oligarchy. Since they've been ousted by their own membership, they can claim leadership all they want, but unless the majority of RoK's remaining members even want a Joe/Bob leadership, they're SOOL.
Chalk all of this up to a poorly written charter, a poor choice of government, and poor FA decisions (that is, if the RoK membership overthrew Joe/Bob because of such decisions).
I stand by my alliance in supporting RoK's membership and recognize Adel as the new leader of RoK. However, I fear RoK's time may be up shortly.
