A few issues & questions

I was wanting to know if its possible to remove the “join clan” button on certain teams? Also is it possible to create a team and then manually add the members to the team without them actually being users? Another question I got is can the “Founded” date be altered to a past date, not the date that the clan is created?

I have also tried to find out how to add “games” but have been unable to find out how to, so any help would be appreciated with that.

I am also getting the bug in the attached picture. It occurs on all clan pages.
