You got an invite

You don't have to download anything to answer. The steps go from your reply to what an account adds, and each one links to the article with the detail.

1. 1Open the link and type your name. Leave your email too if you want a reminder the day before and a heads-up if the plans change. For texts, tap Add a phone number. Texts reach US and Canadian numbers only.
2. 2Tap Going, Maybe or Can't go, and your reply is in. To change it later, open the same link on the same phone or browser. See RSVP without an account.
3. 3Once you've said Going or Maybe, Add to calendar and Directions sit right under your answer. The same link then shows the host's updates and photos from the event. See Event updates and reminders.
4. 4Want the rest of the event? The chat, the whole photo album and who's coming are for accounts. Tap Create an account on the invite and your RSVP comes with you. See Create your account.
5. 5With an account, the event is on your Calendar, its chat is in your Talk inbox, and you get a reminder a day out and another an hour out. See Event chat and photos.
6. 6To see your Joinue plans in the calendar you already use, tap Subscribe on your Joinue calendar and add it to Apple, Google or Outlook. See See your calendar and sync it.
