This is about a software downloads facility where I want account registration for new members during the order confirmation stage. I have read the documentation about this, but have questions:
1 should I use register_member="" just like that or is it register_member="true"
2 do I have to require the email address via parameter or does the presence of the register_member= parameter cause that?
3 the docs say that an account will be created based on the email address. What feedback is provided when this actually happens?
4 what happens if a returning customer goes through another order process? The docs only say "and the email address must not already be used for a member account." Does this mean an error will be generated or is there a way to steer the user to login before completing the order?
