As far as I know, there is no way to say write code to "make the type-in block 10 spaces longer if a prefix is not selected."

Perhaps there is someone who does know enough to inform our forum? If I and our forum understand correctly - it would appear that the introduction of the so-called optional prefix seemed to have caused the discrepancy between the number of spaces available for title creation for anonymous volunteer fellow posters and us ordinary posters - in the first place.

So it must be possible to also now include the prefix block for in the editing screen which will result in all posters having an equal ammount of spaces available for thread title creation?

Or indeed to remove the prefix block from us ordinary posters - which would also have the end result of all posters having an equal ammount of spaces available for thread title creation. The concern - after all is only for clearer thread titles and for all posters to be seen to be treated equally on our forum.
