A few Rally-related links I've discovered. The BVDM is an essential one to watch if you're interested in "doing" the Elefant. If you come across any broken links, please let me know.

BVDM The organisers of the Elefantentreffen, this should be the first port of call if you want to know the full details of the Rally
BMF The BMF seem to be the first of the English-language sites to post news of the Elefant
Yahoo groups The Elephantine group on Yahoo turned out to be the friendliest and best source of information for the Rally. Please, only ask to join if you really are serious about the Rally.
