Dear nrpd10267,
Please follow the below instructions in order to dissolve your Guild.
Instructions:
Click on Global (Three silhouettes)
Then, click on Your Guild (Centre Shield)
Then, go to the Administration tab (Top right hand corner)
Finally, go to the bottom right hand corner and Click Dissolve
These steps should enable you to Dissolve your Guild. If you do not understand any of these steps, please comment below and I will get back to you as soon as I possibly can. If these steps continue not to work, as naterichster said please right click and contact support for further guidance.
I hope this helps.
