I've made some updates to simplify and reduce the number of clicks it takes to sign up to a regular calendar event. I've also updated the way that signed up members/characters are listed. This is something that has bothered me personally for awhile trying to organize my own guilds. Essentially nothing about the functionality should change, just quality of life UI updates. I've made this update mostly for V5 because it can accommodate a more modern styling. I've left Rapid Raid alone because of how deep and complex those features go, I did not want to break anything there.
Please let me know if this update removes any particular feature or setting you've used before. It shouldn't have any negative effect on anyone's operations, but there may be something that slipped through the cracks on me.
TLDR: Character and Member sign up UI for regular events has been updated!
