Server notice channels in ircd v2.9

In IRC server version 2.8 there was usermode +s, which controlled showing server notices to users. In server version 2.9 that usermode has been removed, and as replacement there are multiple notice channels. These channels start with & prefix, and normal chat isn't possible on them.

The new channels are:

&ERRORS
Error messages concerning server and network.
&NOTICES
Informative and administrative notices from server.
&KILLS
Kill messages for users, collisions.
&CHANNEL
Channel mode desynchronation warnings.
&NUMERICS
IRC server protocol errors between servers, misrouted replies.
&SERVERS
Introduction of new servers and splits of existing ones.
&HASH
Server internal hash lookup table statistics.
&LOCAL
Server local configuration warnings.
&SERVICES
Introduction of new services and quits of existing ones.
