There are a lot of domain names for all the Wikimedia projects. Some are the property of Wikimedia, some of friends of Wikimedia.
http://meta.wikimedia.org/wiki/Domain_names
I have the impression that the dealing of requests regarding domains is done ad hoc by diffrent people.
To make sure that the overview is not lost, the usernames and passwords for those domains, it is not forgotten to renew domains, to be a contact person for friends of Wikimedia who are willing to transfer a domain and for requests for buying new domains, it would be good if there where one person responsible.
