That's okay, we'll just come say hi when we're awake during your timezone. Just don't answer the creepy guy asking how much oil reserves your country has.
To the people worried about losing the content of your channels, there is a chrome extension called Discrub that can get all the content and compress it for you.
Used it to transfer the stuff I posted (pics, memes, links to music videos) to my matrix.
I have heard there are "bridge" programs that transfer what's posted on discord to your matrix channel but I haven't found it yet.
I've only heard of bridges that are set up to enable, say, IRC and Discord channels to replicate to a Matrix channel, and vice versa. So we can have a conversation with you using Discord and me using Matrix, which appears to you as a Discord channel and appears to me as a Matrix room.
