Logout and login should be only 3 clicks and a “re-render button” would take the same or more than that because we would need to put it in your forum profile.
This is not really high priority for us to address because of the simple existing workaround. In the future we may auto-update your forum profile as you change it on the main site.
Marking this as the solution since this thread poses a proposed solution that we won’t be able to implement. In the future, please write threads about problems, rather than proposed solutions!
