Account channel profile
Some notes for anyone that may be similarly confused.
From default account, create new profile which will be able to have limited visibility. The first profile of the account is the default, public, profile visible to all.
From 'channel manager', new channels can be created. However, it has been discovered that previous channel names cannot be used. For example, a channel is created on a hub, then the hub disappears. So, there is no documentation from the programmers (as always!), but a new channel should be created and then the option to export the channel should be completed as soon as created (a text file with 'json' suffix). Then a channel could be imported from this file. Apparently the process takes time, but no progress indication is shown, no idea how long it takes. After many minutes, the new channel imported, fails to appear.
