Here is a pattern that plays out constantly in group scheduling. Someone receives a link to a WhosFreeWhen event. They open it, have a look at the calendar to see when everyone else is free, find it interesting, and then close the tab without filling in their own availability. They did not forget to respond. They just got distracted mid-task.

A day later the organiser is wondering why this person has not responded. The participant does not realise they forgot. Nobody wants to send a pointed individual message. It is an avoidable friction.

The "You Haven't Responded Yet" banner is designed to close that gap.

What the Banner Shows

When a participant opens an event link and has not yet marked any of their own availability, but at least one other person in the group has already responded, a dismissible amber banner appears at the top of the event page:

"You haven't marked your availability yet. 3 others have already responded, add yours to help find the best date!"

The banner includes a "Mark availability" button that switches directly to the Calendar tab and scrolls to the top, so there is no hunting around for where to go. A single click takes you straight to the action.

A dismiss button lets the participant hide the banner for the rest of their session if they choose. This is for cases where the person is just checking the event data without intending to fill in their availability right now, or where they are checking on behalf of the organiser.

Why This Works Better Than a Follow-Up Message

The core problem the banner solves is the gap between "I saw the event" and "I actually filled it in." This gap is not usually caused by unwillingness. It is caused by opening the link, getting interested in the data, and then closing it before completing the intended action.

Showing the banner at the moment of that open and drop-off is precisely the right intervention. It catches the person when they are already looking at the event, gives them a reason to act (other people have already responded), and provides a one-click path to doing so.

A follow-up message from the organiser a day later faces a much harder task: the participant needs to reopen the link, remember what it was for, and find where to add their availability. The banner removes all of that friction by prompting action before the session ends.

The Right Level of Assertiveness

Group scheduling tools sometimes err toward being too passive (no reminders at all) or too aggressive (emailing every participant repeatedly). The banner is deliberately positioned in the middle.

It is amber rather than red, which signals information rather than urgency. It appears once per session, not on every page load. It can be dismissed. It does not send any emails or messages to anyone. It is a quiet, contextual nudge rather than a public announcement.

This design respects participants who are just browsing while still catching the large number of people who genuinely intended to fill in their availability and simply forgot.

For Organisers: Less Chasing Required

The banner also reduces the organiser's workload. Every time it converts a passive viewer into an actual responder, that is one fewer person to chase up manually. Over a group of ten people, if two or three respond to the banner rather than needing individual nudges, that is a meaningful reduction in the admin overhead of getting the event confirmed.

Frequently Asked Questions

Does the banner show if nobody else has responded yet? No. The banner only appears when at least one other participant has already submitted their availability. Showing it in an empty event would not provide the social context ("others have responded") that makes it effective.

Can the organiser turn this off? The banner is on by default and cannot be configured per-event at the moment. It is shown to all participants who open the event without having responded.

Does dismissing the banner affect the organiser's view of who has responded? No. Dismissing the banner is a session-only action. The response list in the organiser's view is not affected by whether a participant has dismissed the banner.

What if I have partially filled in my availability (some dates but not others)? The banner checks whether the participant has marked any availability at all. If you have filled in at least one date, the banner will not appear even if many dates are still unmarked.

Small Design, Real Impact

The "You Haven't Responded Yet" banner is a small design detail, but it addresses one of the most common failure modes in group scheduling: the open-and-forget pattern. By catching people at the moment they are already engaged with the event, it turns a browse into a response without any extra effort from the organiser.

If you have an active event on WhosFreeWhen, ask a participant to open the link and see if they notice the banner.
