Guild doesn't have GM in WCL

Our guild (v cute, Illidan) doesn’t have a GM in WCL. We are trying to use WCL to recruit some new players for our raid, but I’m the only one that’s listed as an officer in the guild. Is there a way to promote either me or our actual GM to the GM role in WCL so we can promote our other officers to Officer rank for recruiting? Guild is linked below. I am Lindessa in that guild, our actual GM is Xanibtw. My profile is Lindie and Xanibtw’s profile is Xanixo. Xani’s mage, Xanixo, is listed as Rank 0 but he’s not listed under User Management under “Settings” for the guild.
