How can I lock my domains?

Aus DD24 Wiki

If you would like to place a domain name on lock (for example to block unauthorized domain name transfers) please proceed as follows: Select the domain name you would like to place the lock on, on mydd24 mainpage by selecting the check box on the left side of the domain. Please be aware that a lock can only be set on a generic root domain (e.g. com/net/org/info/biz/name) - not on a subleveldomain (e.g. www.example.com). Then please select the command "Lock selected domain" from the drop down command box and click "Submit". Locked domain names will be marked with a small lock icon on the right. Be aware that with some TLDs a lock also implies that no nameserver/whois updates can be made to that domain name while locked. If you would like to remove the lock please proceed accordingly but chose the command "Unlock selected domain" from the command box.
