To change the default prefix the command is !settings prefix [insert]
At this current point in time you can customize guild settings as listed below:
> Message Logs
> Join & Leave Logs
> Required to issue punishments.
> Required to allow users to report.
Custom Voice Channels
> Requires an Admin to own Premium.
Due to how we have setup our backend systems and how to also earn the currency we have prevented usage to customize these:
> This has been disabled due to the link in with the new currency system.
> This has been disabled due to the time it would take us to convert every embed to text.
!settings logs <#channel>
User Join/Leave Logs:
!settings logsUser <#channel>
Change the prefix:
!settings prefix <new prefix>
!settings punishments <#channel>
!settings reports <#channel>
Custom Voice Channels:
!settings voice <#channel>
(TIP: Make sure the channel is the id of a channel section where the voice channels will be displayed)
Sorry but due to how we have our currency systems setup you will not be able to customize your guild currencies.
