How-to delete/Change wiki.netbeans.org account?

Hi all,

Made a typo while registering my wiki.netbeans.org and cannot found a
way to get rid of my wiki account called RickvanderZwet (username:
rickvanderwet, which should be rickvanderzwet).

Reason for deletion/change is the fact that I would like to keep
naming consisted between all systems I am using :-).

Thanks in advance!
/Rick
