One of the many features of our new Discourse based forum is the ability to note a post as solving a problem. As the original poster of a topic, you have the option to select any reply to your topic as a "solution".
To select a reply as a solution:
Go the to the tool bar beneath the reply.
Click the "..." (Show More) icon.
Click the This Reply Solves the Problem check box icon.
Only the OP and Forum moderators can mark a Topic as solved and only one reply may be marked as a solution. Solved topics will display a special icon in the topic list, and the solution will be linked to directly from the bottom of the first post.
