Upload Field

Is it possible to create on the registration form an upload field say for doc,pdf,image types? At present our small club uses a Joining Form with provision to upload a bank transfer payment confirmation for people to join the club and then we have to email them to register on our website. Having them join and registered from one app would be much more simpler.

Yes, CB includes a File fieldtype where you can supply a list of supported extensions. If your site requires payment though maybe consider using CB Paid Subscriptions instead of requiring them to upload a payment confirmation statement as you could then just capture payments and register them in 1 step.
