Hey @smasher_online!
I believe a Nightbot account can only be linked to one Discord server, so you’d need two accounts if you want to use Nightbot in two servers. Here’s a guide if you’re looking for a way to Export your Nightbot commands to save them on your computer!, you can then use the Nightbot API to import your freshly exported commands to your other instance of Nightbot.
Please note that Nightbot isn’t primarily made for Discord, Discord support is a side-car, if you’re only looking for a Discord bot, you’ll be better off with a bot specifically made for the platform.
