Our organization would also like this for people to sign up for different program notifications such as our low cost spay and neuter program, our upcoming events, etc.

This would be really useful, especially if a custom field could be mapped to a custom field for each user. I can see how this would be complex to implement in software, though, so even just allowing a form to have custom fields that are sent in a free-text "notes" field would be pretty good, too.

My non-profit is interested in using a sign-up form to collect contacts of interested sponsors. We would need to be able to add a company name for this to be a viable option!

My non-profit relies on collecting mailing addresses and other information. We NEED the ability to add custom fields as many organizations rely on this basic information. So my vote is to add custom fields to sign up forms as soon as possible. Thank you!

This would be immensely helpful for my organization, which needs to segment email subscribers by state/region!

This would be very helpful. We would love the ability to have greater flexibility in the fields and placement of those fields in all the widgets, but especially this signup one.

Echoing this request! We want to know additional information about the people signing up for our email list.

A very common use of this type of widget seems to be signing up to be included in a newsletter. We have a need (and have seen similar comments below) to have volunteers 'sign in' when they arrive to an event or to volunteer. Almost like a 'waiver' that collects their basic info, but may also ask additional questions, or acknowledge terms and conditions. That volunteer record then gets added as part of overall donor management. Custom Fields could solve this problem

The ability to add mailing address and company would be highly beneficial for those looking to build out physical mailing lists in addition to email lists.

Enabling the sign-up form to be customizable, including the ability to add additional contact fields, such as address and phone number, as well as custom fields, would be highly beneficial for our non-profit.
