There is a toggle button next to New Reply button labeled Set Solved or Set Unsolved. This shows the state of the button if pressed. Please set your threads to solved when you determine your thread has been resolved. There will be a green check mark in the thread listing after you do this. Only thread authors and team members can set threads to solved/unsolved.

A solved state does not close the thread. You may still post answers on solved threads.

Please utilize the solve button. If everyone selected the solve button when their questions were answered, then people who answer questions could focus on those threads unresolved even if there are posts on the thread.
