Kristján Einar Guðmundsson is the actual name of Kontinuum drummer (check it here: https://www.facebook.com/pg/kontinuumice/about/ ), while he's present as Kristján Guðmundsson.
The problem is that he's already present as he's the same drummer of Potentiam and other bands.
He is this one: http://metalstorm.net/bands/bandmember.php?member_id=9124
So the other profile ( http://metalstorm.net/bands/bandmember.php?member_id=63908 ) should be deleted.

I don't think I can suggest such an edit by the actual interface, right?
As long as this is not the first time I came across such a problem, I think it would be usefull to have some sort of "suggest merge" button, to report this issue to the staff.

Fixed

Next time use ubb code for links
You can report it here!!! or PM to any staff member or me

Now the drummer for Fortíð and Einar Potentiams solo projects.

They're brothers Kristján and Einar, I've been waiting for years (a decade, almost two) to see what happens if they were to team up
