dear MJSU! 
so I had the idea that after dc join username u get a message from the bot with the link. My lazy community tend to find it too difficult to remember those 10 letters to join discordserver over the browser

Fun Fact: i did the change to the cs file on my last server in February (with the 2x "+ new message" tho) and it never worked. after getting ddosed I quit my provider and now uploaded the whole server again to a new provider. The feature suddently worked but it was with the old Discord Link.  I deleted the whole thing and reinstalled it and changed discord API. Still the old discord server link. It seems like once it got saved somewhere it cant be arsed.

Maybe you can use your magical cs-skills implement this feature it into the config file as i hope to have convinced you with the benefit it brings or have an idea to fix my problem?
