I have COWOA installed and working on my site (now that I got the correct version).

https://westpac-ptg.org/zencart

It is working the way I want except the conference director finds it too confusing to include the option of creating ZC account. She is probably right because for this use (conference registration) it is highly unlikely that any users will want to log back in for any reason. I've already moved the code for COWOA to the top of the page and made the fieldset blue to make it more prominent, but she wants all but that and paypal checkout to be gone.

In looking at the code in tpl_login_default page, it is difficult for me to know what code I can safely remove to take out both the zc login and sign up. There is this type comment:
<!--BOF PPEC split login- DO NOT REMOVE-->
before the section where I would have to remove code. Makes me nervous.

Since the site is now live, I'd rather not experiment too much. Is the code for ZC login and ZC signup required in order for COWOA to work? Or do you think I can safely remove it?
