Today I accessed the ST channel “welcome to Domino Workspace” and I found out that everyone, except admins, has a role of “viewer”, which means we can’t send messages.
I assume is an error, else it would defy the concept of chat itself.
Hi Roberto, that seems to be solved.
I just tried and it worked for me 
Cheers

Yes, I tried a few days ago and HCL fixed it.
