Is there a mailing list specifically for questions about working with Unbound internals? Questions could be asked about how to do X with mesh_* or whatever. Or is unbound-users the most appropriate place for this still?
Additionally is there an IRC channel to idle in with other like minded Unbound users?
At NLnet Labs we do not use an _official_ #unbound IRC channel.
Discussions about unbound internals are rare, lets have them here. We can spawn off a list if there seems to be popular demand or the esoteric discussion start to take to much of the bandwidth.
