Hi everyone - we're really sorry about this problem. The tech team have been trialling a new feature where thread titles have to be 20 characters or more. We've decided not to go ahead with this (we can tell our users aren't too keen! ). The trial is over now, so threads should be back to working normally. Let us know if you're still having any problems. In future though do post things like this under the Site Stuff topic - it helps us see your threads quicker .
