What is the difference in bookmark or subscribe options between main message and topic

Hi Parshant,

You can bookmark boards, posts, articles, etc., so that you can revisit them later and it is easy to find them. To view and manage your bookmarked content, goto My Settings -> Subscriptions & Notifications -> My Bookmarks. You can also add the Subscription bookmarks component to user profile page for quick access for registered users.

On the other hand, subscribing to community content (boards, posts, etc) will ensure you are notified when new activity happens on the subscribed content.

Hope this helps!

Thanks,
Srujana.
