@ CrocoNuts - Is the change of leadership documented on the thread? If so, perhaps the new leader could appoint a new thread holder, if he doesn't want to do it himself, and ask them to start a new thread, requesting here that the existing one be closed.
@ CrocoNuts - It is highly unlikely that Jagex would lift a forum ban just so a thread could be updated.
The reason I asked if the leadership change was documented or mentioned on the thread, is because if it was, whether done by the OP or someone else, that would make it easier for the F Mod Team to follow the succession and be assured that any request to close the old thread so that a new thread could be made was coming from someone with the authority to make that request for the RP group, rather than from someone wanting to cause trouble to the group.
