Voidberg and I are giving a second chance to the lazyreg module. Currently there's no such functionality in drupal, and it would be great. For now we have in plan allow the creation of a 'temporary account' to test the site features, and give the user chance to keep it, filling the missing account information, or forget it, just login out the site.
Is there something we are missing or we should consider? do you know of something being implemented about this?
Thanks in advance.
