Within Teamwork, you can create a project chat channel for the project directly from the project's settings.
A Chat channel will be created in your associated Teamwork Chat account.
You will first need to enable Teamwork Chat for your account. Once your Teamwork Chat trial expires, you will need to create a Teamwork Chat subscription to use this feature.
Note: Teamwork accounts using the Deliver/Grow subscription tier have access to Teamwork Chat as part of their subscription.
Go to the Settings area of your project and select the General subsection.
At the bottom of the General Settings panel, you will see an option for a Project Chat Channel.
By enabling the channel feature in the project settings, a project channel will automatically be created in Teamwork Chat, giving all members of the project access to it.
Note: Only project members who are marked as active in Teamwork Chat will be synced.
Once it has been enabled, you will then be able to access the channel through a link in the settings.
Note: A channel cannot be disabled from within Teamwork. If you want to disable it, you will need to unlink the project in the channel's settings in Teamwork Chat.
