Domain grabbing can be ugly and this one has been taken for defensive purposes only - anybody who happens to be called or related to Blasum can have an account here for free or at provider cost (if causing heavy traffic), if he or she is having time to help with the administration ;-). For that, I will happily sign any legal domain name sharing agreement if you are concerned about that ...

Tobias Blasum is doing some Blasum genealogy at www.blasum.org.
