Auto-tag rules enable you to automatically add a tag to customer accounts when they register on your site.
To create an Auto-tag Rule:
Login to Wholesale Now
Click Auto-tag Rules in the main menu
Click the Create an Auto-tag Rule button
Give your rule a Title (only you will see this) and choose a tag to add to new customer accounts.
Click the Save button
And you're done! New customer accounts will now be tagged with the tag you specified.
