Hi!
If you find that one or more forum rules have been violated in a message, you can signal this message to the administrator by clicking on this button located at the top right of the message.
You must then explain the problem in a few lines so that the forum staff can take the appropriate measures. Once your report is sent, simply wait for a moderator or administrator to process your request. All this remain private. Nobody will know that you warn the administrator.
That's all.
