There is such a server for developers around Steem, but it is not for general Steem comunity really.
To be honest, I don't know Discord that much. I was thinking that only a majority of people need to add the bot and that these users already know to do so in case they are administering a server of their own.
In any case, thanks for the details you've posted, I might add these instructions later when I have some spare time.
Adding a button with link as posted above should be very easy and already a great improvement. Same way as Enable button works in Telegram section, I guess.
Anyway, in case someone lazy stumbles across this comment. This is an invitation link to my forever-alone server with SteemWatchBot added: https://discord.gg/xFqNCaZ
I don't plan to manage the server in any way, so be warned. Expect total anarchy and chaos.
Ok, adding the link should be easy, thanks for the suggestion.
