The welcome message displayed beneath the affiliate manager's photo in the affiliate panel must be enclosed between ## and ##.
To edit the affiliate manager's information, including the welcome message, in the merchant panel, navigate to your merchant name > Change affiliate manager info visible in affiliate panel. The welcome message should be formatted as follows:
##Hello and welcome to our affiliate program...##
If you have updated the welcome message, you will need to add it as a new translation. To do this, go to the merchant panel and navigate to Configuration > Languages and Regional Settings > Languages tab > Edit language (in the Actions column) > Translations tab > Add custom translation.
NOTE: There is also a Home screen welcome message.
