As someone who still uses IRC daily please understand that telling people IRC is a replacement for Discord is utter nonsense
IRC does not
- let you post images or other files (DCC send doesn't count even if you somehow get it to work)
- show link previews
- do voice chat
- do screen sharing
- have offline messaging capability
Please stop saying IRC is an alternative to Discord. It's not. Or at best it's a very shitty alternative
