XF 2.1 Change user titles manually


New member
I already have a ladder titles system.
But I would like to upgrade the title for some users manually even if they don't meet the conditions to have the title.
I don't see a field with the title, so I guess I will have to go to the database to edit it manuall, right?
Two questions:

1.What is the table storing the title?
2.If I change the title manually on the database, Xenforo will reset it in the future?
