Squarespace do not offer a forum feature for their websites or Member Sites at this time. However, there are a range of third party forum platforms available.
For example, Squarespace built this forum using Invision Community using a subdomain ("forum.") of their main URL.
You can also use a third party service like this to create a forum using a subdomain of domain you use for your Squarespace website. There are many other third party forum providers including Discourse and Flarum.
Squarespace doesn’t use this forum to track demand for new features or to accept feature requests so if you'd like to request a forum feature, you are encouraged to raise a ticket through Squarespace Customer Support 🙂.
