<@U010VKHDSGM> and everyone: I'm about to unsubscribe from <#CDRCA57FC|> because the volume of chatter is too high. Can you create a new channel #announce and put announcements there?

Hi <@U013AAPGVHA>. I understand your frustration. Unfortunately, we cannot force users to use other channels. The intention of <#CDRCA57FC|> is as the topic says, for community-wide announcements and work-based matters. Please mute this channel or advise further on what you would expect and we will try to improve best we can. Thanks.

I will change the topic for now to remind people that troubleshooting issues should be made in the <#C011C9JHN7R|> channel.

We can restrict the posting permission on <#CDRCA57FC|> as `admin` only. Ref: <https://slack.com/help/articles/360004635551-Manage-channel-posting-permissions->
