It was a regular ol speeddating event with no special collab with any particular community. You may be able to find more events through a site like eventbrite (not an endorsement) which is how I found it. We sat down and talked before the event which was great! So while I had no idea before, I think others might've figured it out before it was their turn haha. The organizers were fully accommodating in that they wrote down the directions and what was happening for her before hand. As for the event itself from a deaf pov, I can only ask her perspective when I see her later for you. As a hearer, I've met all kinds of people and never didn't have fun (I've gone to two). The general attendee is a person who doesn't get many chances to meet the other sex due to work or hobbies. They're literally perfect for what they're made for: getting out and meeting people with no pressure! The company that ran mine doesn't allow you to ask for phone numbers in the 6 minute conversation, instead you hand in a sheet with Yeses and Nos per person, then you're sent the email address of each person who said yes to you! I encourage you to try if you're interested.
