username custom field

How would I get the username as a custom field during registration? Or at least, include it in the record so when I export, it shows up. At the moment, I have to have the registrant fill in a custom field with their call sign (which is their username) - I would like that to auto-populate from community builder if I can.

I don't think you should do that. If you need username, you can edit the csv export function in the extension to export that information

It is not logical to ask users to enter username when they are already logged in. You can submit a support ticket and we will be happy to help with the modification
