I was working with importing my user subscriptions from mybb for user upgrades.
I created a sample one so I could see the data that it was looking for so I could use that as a base to start my code.
One thing I can't figure out is the "extra_group_ids". When I add the sample via the UI, I add the usergroup "Premium Members" which is usegroup ID 11, however the UI adds extra_group_ids of 3131
I can't seem to make sense of this.
Any ideas how this is formed so I can use this for the process of adding these user upgrades?
