While all channels share a common purpose, they come in various types. Discovering the nuances can assist you in crafting the ideal space for your conversations. 

This article dives into the significance of both public and private channels and what is a Slack channel. Explore the distinction between public and private channels in Slack, where channels facilitate discussions focused on specific topics within workspaces. 


What are Slack Groups?

Slack groups operate like direct messages but can include three or more people. Forming a group involves adding members to an existing direct message or creating a new group with selected individuals for private messaging.

In terms of functionality, Slack revolutionizes company communication, replacing traditional email with a faster, more organized, and more secure approach. Channels, replacing one-off email chains, offer a streamlined way to create, join, and search for communication threads.

Slack channels are dedicated spaces for team members to engage in topic-specific conversations, share files, and even initiate huddles (limited to 2 people on free plans).

In paid workspaces, the versatility expands, allowing users to seamlessly exchange video and audio files within channels and initiate calls. The list of channels appears on the left sidebar, marked with a # or a padlock icon for private channel on Slack.

Commencing with a default #general channel, where all members auto-join and can't be removed, customization is in your hands. 

Free plans retain the most recent 10,000 messages in a channel's history, accessible through the search function, while paid plans offer unlimited access to the entire message history. Slack channels are your team's dynamic digital hub tailored to your collaborative needs.

  • Ideal for exploring the platform and deciding if it suits you.

Why Set Slack Groups To Private?

Confidentiality of Sensitive Information

Setting Slack groups to private ensures the confidentiality of sensitive data. This level of privacy prevents unauthorized access, fostering a secure environment for discussing and sharing confidential information within a trusted circle.

Controlled Access for Security Reasons

Private Slack groups allow controlled access, enhancing security measures. By restricting entry and requiring approval, organizations can mitigate the risk of other individuals gaining access to sensitive discussions, files, or data.

Selective Content Sharing

Private Slack groups provide a selective space for organizations with varying levels of information sharing. Members can share specific content within the group, ensuring that sensitive or strategic information is only accessible to those with approved access.

Public vs Private Channels

Slack workspaces consist of channels that serve as message boards or chats with specific purposes, like #hiring or #jobs for job postings. By default, channels are public but can be set to private by workspace owners or administrators. Once private, a channel can't be converted to public.

Private channels allow administrators or specific teams to discuss sensitive information. Slack recommends publicizing most channels to encourage open communication and collaboration within a company. Slack Public channels foster a culture of sharing, while private channels cater to more confidential discussions among specific teams or communities.

What is Shared Channels?

Shared channels in Stanford Slack provide a seamless bridge to collaborate with external organizations. This feature, powered by Slack Connect, allows you to connect with vendors and partners outside Stanford without needing guest accounts. You can set up shared channels involving up to 19 organizations, enabling open communication.

Whether creating new channels or sharing existing ones, the experience mirrors regular channels. You can send messages, share files, and initiate calls within your Stanford Slack workspace. 

Remember to give shared channels clear names, perhaps adding a prefix like "#ext-" for clarity. Identify shared channels with a double diamond icon and explore details to see the collaborating organizations. 

Why Set Slack Groups To Private?

Creating private Slack groups or Slack private channel to public serves various purposes, driven by the community's need for control, quality, and privacy. Here's how to join channels on Slack.

Screening Potential Members

Private groups often employ application processes to assess a potential member's suitability. Questions about employment, motivations, and location help ensure a good fit, maintaining the group's integrity and fostering relevant discussions.

Membership Fee

Running a thriving Slack community involves effort, and a membership fee may be necessary for enhanced features. This fee supports the community and allows access to premium features, ensuring a richer experience for members.

Privacy and Comfort

The private setting offers members a more confidential space to connect, share, and discuss. It fosters a sense of comfort for individuals to freely exchange experiences, questions, and updates among like-minded peers.
