The -myaccountarticles parameter is used with the $IF command to determine whether the logged in user is subscribed to any Find Answers articles. This presents the same list of Find Answers articles that the user would see from the /MyAccount.aspx?mode=subscriptions page within iService as shown below.
Example:
$if -myaccountarticles$
Yes, you are subscribed to Find Answers articles.
$else$
No, you are not subscribed to any Find Answers articles.
$endif$
For an example of using -myaccountarticles to generate a table of available lists, see the My Account Subscription example.
