Not sure if you saw my reply in the other discussion you created - I am unable to find my "secret customer group". but I have copied it here for your reference:
For more information on where to find your customer group I think you will find the MyJive Secret Support Group Administration FAQ document helpful.
That being said, reviewing through your user account, I am not showing you as a member of a customer group. As such, I would recommend reaching out to your Community Admin/Manager, as they should have access to invite you into the customer group associated with your company or submit a case on your behalf.
