If you're concerned about a post's context or content: that it's not complying with the forum's goals and standards, you can Flag it, which will notify Administrators that it might need some action taken. You may be expressings others' concerns too.
HOW TO
First click the three dots at the bottom right hand corner of the post, which will expand the post's menu.
Then click the Flag.
Then, on the reporting page that pops up, select the appropriate category with which to deliver your message, and send it. It will remain private.
Thank-you.
Admin.
