Having a special section in the Event creation page that allows the event creator to label each event according to popular games such as [WoW] for World of Warcraft and [FFXIV] for Final Fantasy XIV So that when people set up events in large communities they can easily see which they are signing up for.
Suggestion for the suggestion: A tag/flair system for the website that allows you to mass-tag events. The tags themselves can be different colors to help differentiate them. You can filter the event list/calendar (on the website) by tag. For the discard side, perhaps adding/removing a tag could automatically edit the event's title to add the tag as a prefix or suffix. edit: I guess this suggestion already exists here: https://roadmap.sesh.fyi/feature-requests/eiulybj7ukomvrg7qh1v68g3
