Hi,

I add an account called manifesto here.
I could not use it anymore and I register this new one (nosuke) but I wish to use the old one.
It is strange I cant migrate nor login with old one.

How can I do ?

Thanks

This is because the forum has migrated to KDE Identity for authentication. As you may have noticed, your existing forum username, "manifesto" has been retained as your forum display name as your new Identity account was automatically mapped to your existing forum account. This migration was necessary to ensure a consistent experience across kde.org and to improve account security.
