We released the feature to allow the ability to use the creator's name in the channel name, whereas before it was ticket-0000 it can now be dapper-0000 and so on.
To set this up you need to go to our panel, once logged in click "Tickets & Embeds", click edit on the Embed you wish to Edit, then Edit the indiviual Tag, in the "Name Convention" put "{username}". Looking like the below.
If you wish to have the ticket names show like "support-username" then stick it like "support-{username}" in that box.
There we go, all done :)
