There's a mailing list devoted to the DRBL project maintained here at Croco.Net. The list is members-only, that is, you need at least to have your own DRBL node to join the list. The list owner reserves the right to refuse anyone's subscription request.

Currently, the language of the list is Russian but this will likely change when someone who doesn't speak Russian join the list.

The list is named drbl-members@lists.croco.net. In order to subscribe the list, send a message with the word 'subscribe' to the address drbl-members-request@lists.croco.net. You'll promptly receive an automated answer from the mailing list robot which will contain the instructions to follow to complete the subscription procedure. Note that it could take some time (up to a day or two) for the list owner to approve your subscription.

There are some certain rules for the list. Here they are (this text is also sent to you when you subscribe the list).
