This is a freely hosted event tracking bot. You set a event channel and a log channel then any created events will be grabbed by the bot. From there it wll handle all event tracking by sending DM reminders and then a final tag into the event channel just before. It also allows custom messages for the DM reminders and the 10 Min reminders and also allows the owner of the server to set when DM reminders and the channel reminders are sent. From 2hrs before the event to several hours longer or shorter. 

Its also has a "booster" function. You add a booster role to it, apply it to a user who can then add a list of games and trigger words. When the word is said in a channel the bot then will tag all who have the keyword added into their name
