My name is Alex and I am the developer behind the Discord bot "Raid Organizer".
"Raid Organizer" is a bot that let's you create and organize events/lfg's/raids from within Discord.
Yes, we have a website which may make some things easier... but you are not required to go there and use it at all. Everything the bot is able of can be handled from within Discord!
Thats also one of my main goals. Making a bot that is easy to handle and does not require you to use multible platforms. Since you are already using Discord for your voice and text communication, why not for organizing your events as well?
If you like what I do you can buy me a beer.. because, you know.. programming is easier if you are a bit drunk ;)
