A bug has been reported wherein members using the latest FireFox web browser cannot see the WYSIWYG message editor when using quick reply or full reply modes. This has been reported by others to the software developers and a fix is imminent. In the meantime you can use any of the following browsers with success: Google Chrome Apple Safari Microsoft Internet Explorer Or you can turn off the WYSIWYG editor by accessing your personal settings on the forum and making the necessary changes. I will advise once the bug is corrected in the forum software. Hopefully later today.
