A guest is recognized when he opens the event website using his personal link that has '?guest=<some unique value>' in the event website URL. This part is added automatically right away as the guest RSVP. It means that guests can signup for items, answer polls, leave comments and etc only after RSVP'ing.
To open the event website as a recognized guest after the guest left the website he needs to use the personal link from an RSVP email confirmation our server sends to each guest upon RSVP. The email can get to the Spam/Junk/Updates folder so he may need to check those folders.
If there was no such email found the guest needs to open the 'My Events' page (https://www.partylabz.com/account/myevents), enter his email, then auth code that our system will send to him, then click on the 'I am guest' button on the top right corner of the page, locate your event and click on the 'Open' button.
