How can I ask custom questions to certain members only?

Any custom field can be added to your enrolment flow for new members. Better yet, any custom field can be added to the enrolment flow for members purchasing and/or renewing specific plans only:

1. Log in to your admin panel
2. Navigate to Settings > Plans
3. Choose an existing plan, or create a new one 
4. Scroll down to the section titled "Collect Extra Info from Members who Select this Plan"
5. Click "Add Another Field" and select your field*
6. In the Display Context area, choose whether the question should be asked when a member is signing up ("signup") or renewing ("renewal") this particular plan
7. Save your plan
