Tweak to Volunteer RSVP button
Having a button for volunteers to RSVP is great, however it's quite confusing for those wishing to attend the event even if there is a link or button in the text for them to go to EventBrite.
My suggestion...when we're setting up an event RSVP and choosing Volunteer instead of participant, it would be more helpful if the button it creates in the right sidebar says RSVP as Volunteer instead of just RSVP. The text above the button should also reflect that it's to volunteer. See my examples.
