Hello Afflygal,
I'll start this message by saying I hope all goes well, best of wishes and you have my prayers for a successful surgery and fast recovery.
In terms of us manually conducting a guild name change, unfortunately we do not have the ability to do so. If we did, we would have done that already.
That is the reason why we had to set the Guild name change special service for free for a limited time.
Rest assured, your guild will not be deleted, worst thing that could happened is your guild maintaining the @RN or @JN.
As much as I would have loved to help you or ShadowAce or anyone with a manual guild name change the best thing we could do was offer a free guild name change special service for a limited time.
Changing the name of the guild manually could potentially break the guild and bring tons of bugs to those within the guild, reason why we don't have the ability to do so.
