In the Collaboration Hub, Velocity Edition, I am wondering whether it is possible to add more advanced layout to the welcome message, or add a hyperlink.
While you can customize the Welcome Message based on specific audiences, i.e. you could allow one group to see a different message than another group, the message itself is limited to plain text without advanced layout formatting. Hyperlinks are also not possible at this time.
