I have two techniques for you to try:
1 - Login to the forums and go to the main page -- forums.ni.com. Scroll to the very bottom and you will see your subscriptions. The board name will be displayed along with the subscriptions that are displayed on this page. The problem is that not all your subscriptions will be displayed here if you have several.
2 - Login to the forums and go to the Subscriptions tab in your profile. Hover over each link and note the board.id number in the URL. The links to the C++ board will have board.id=231. You could also click on each link and look at near the top of the page in either the breadcrumb or the title of the page to see if it is in the C++ board or not.
Once you have found all the subscriptions, click the checkbox next to them and then click the button to remove them.
If you have additional questions, please let us know.
Thanks!
