There has been a long-running issue with posting messages here on the forum, the main issue would be using ellipses in your post would often cause it to stop your post from being able to be submitted. The web team have done some excellent work and we now believe this issue to be fixed!
If you could try it out below, or anywhere on the forums... Please do and report back!
From initial testing, it does seem to be the case. @Clumsy-George if you're out there :D I think you should be free to post again!
