A. In the 1.3.9a includes/modules/create_account.php, about line # 323 appears a line that begins with the code:

$zco-notifier->notify

I notice in all the other merging I've done so far that this phrase seems always to be replaced with:
This->notify

Should I change the former to the latter?

B. I'm in process of merging FEC v1.8.0 into 1.3.9a

There are many instances in the 1.3.9a /create_account.php file where 'login' is changed to 'create account'.

But there are also large blocks of unique code in the FEC compaable file that use 'login', , for instance //shipping down around #300, so if I copy those blocks over into 1.3.9a will that be a problem....should I edit those instances also to 'create account'.
