Hi James,
Lithium Communities are enterprise level brand communities and therefor our offering is a bit different than other forum or board software out there. Particularly we don't offer a free subdomain registration where you can set up your own Lithium Community for free. We do offer demos though and part of a customer's evaluation process usually involves that we set up a stage instance for us together to work out the right setup.
If you are representing an interested prospect then the first step is to always get in touch with us via the "Contact Us" link that Tariq already shared. Our team will help you find out if Lithium is the right offering for you.
If you appreciate my efforts, please give me a kudo ↓
Accept as solution to help others find it faster.
