Every optional field has the same three choices: **Not asked**, **At sign-up**, or **After joining**. Email, mobile and — for a paid club — name can't be changed here; birthday and postal address can.

## Steps

1. Open **Your club**, then [**Settings → What you ask members**](https://app.useflub.com/manage/go/what-you-ask-members).
2. For **Birthday**, choose **At sign-up** to ask on the join form, or **After joining** to ask later on the member's own page.
3. For **Postal address**, choose the same way. Choosing either one opens **Countries you post to** — leave it on **Anywhere**, or choose **Only these countries** and add the ones you post to.
4. Under **If someone can't give an address**, choose **Let them join anyway** or **Require an address to join**.
5. Press **Save changes**.

## What happens next

A birthday asked **At sign-up** only actually appears on the join form once you have a birthday offer set up under [**What members get**](https://help.useflub.com/your-club/offers.md) — until then, nothing changes for guests. Asked **After joining**, it's a single question on the member's own page instead.

A postal address works the same way at sign-up, with a postcode lookup. **What members are told** under the address field is written for you from your country, and you can edit it to sound like you.

Changes only apply to new members — nobody already in your club is asked anything retroactively. The strip at the foot of the page always shows exactly what your join form asks for right now, before you save.
