The RSA Sustainability network use Slack as its main online system. The key features are: * channels for general chat among network members, and for work in sub-groups around topics or projects. These may be public and open to everyone in the network, or private to a group. * direct messaging one-to-one or in small ad hoc groups * file uploads and blog posts

We encourage everyone to use Slack so we have a shared common space. Slack is easy to use on mobile devices, and you can set up email notifications to alert you to conversations.

Sign in at https://rsasustainability.slack.com/ if you have an invite, or email networks@rsa.org.uk for an invite for yourself or someone you recommend.

Choose something like firstnamelastname for your username so people can recognise you easily. Add a photo or other image to your profile.

While you can use Slack through your web browser, it is better with desktop and mobile apps. * Desktop apps here * iOS app link and help * Android app link and help

Here's what Slack looks like on the desktop

• You can be signed in to more than one Slack team, and these will show up on the left
• Channels and direct message options will highlight if there are messages
• Profiles and notification preferences are at the top. You can set yourself as away
• Add files with + at the left of the message slot. You can also add a blog post if your message is a long one (desktop only)
• View files top right. You can also find a directory of members there.

• Look through messages to get an idea of people's interests, then introduce yourself
• Join any of the channels that interest you. You are automatically subscribed to #general
• Check you have set up notifications to suit your preferences - details here
• Get to know people!

• If you hit return while in the message slot, your message will be published. To create paragraphs use shift + return
• Adding @ before a username in a message will send them an alert. @channel alerts everyone. Please use sparingly.
• You can edit messages - mouse over the message in desktop to get message actions, touch and hold outside text on mobile
• You can star messages to keep track of important ones
• Add Google docs rather than uploading Word docs if you want people to read in the app rather than download. You can do this by pasting a URL into the message area
• Use + beside Direct messages to add one or more people to a private conversation. This allows you to create private small ad hoc groups rather than setting up a channel
