Registration gives you several options ...
This link will provide you with a form to fill out; directions appear on the page and further info appears when you mouse over the blue icons. This is the form to upload a photo to have it made into a jigsaw puzzle. Once you register you automatically have a free account with a quota of 10 image uploads. In the near future you will be able to increase the number of photos you are able to upload.
This link will provide several options. You will be able to edit your profile information, view your friends' profile information, send your friends an email or remove friend connections.
If you send an email to the user you want to request a connection with you will be provided a form. This keeps user information confidential and prevents web robots from harvesting email addresses. The party you are requesting a connection with will have to accept your request before the request is finalized.
If you or your friends haven't uploaded any photos your puzzle pages will be blank.
This link will allow editing the information that you originally submitted in conjunction with any uploaded photo. As an example you will be able to change the title of the photo.
