I set up a public chat server on Discord, the invite link can be found in Links section, on the side menu to the left. No registration, no installation, no ads. Just click, join and start chatting in any browser.
I’m on Discord most of the time. My cabin mates will be there this Camp NaNoWriMo season (and every season in the future) and I’ll also invite some friends who are illustrators, writers, editors and roleplayers to the table.
Feel free to join us for awesome writing talk by the #campfire!
