Posts containing off-topic contents (e.g. funny cat videos) will be interpreted as an act of civil resistance against the civil resistance movement and will result in a raised eyebrow by the admin ;-).
To discuss specific topics in channels use #HashTagsWithCamelBackNotation.
To permanently share content consider using external file sharing services which allow a hierarchical folder structure, e.g. Nextcloud.
