Raid Organiser

Hello guys, can anyone tell me a good raid organiser (website) where we can create an event where our members can signin with their roles. I remember we used to use this kind of website back in those molten days, but i cant remeber and find it through google after coming back after almost a decade :p

Are calendar events not good enough?

Calendar is the best way to achieve this. You can always create a spreadsheet in Google Drive and share it with the guildmates to keep the roster organised.
