I use Moodle in the classroom and until Moodle 2.0 I found the Q&A style forum very useful. I would set various questions and the students would post answers. They would not see any other students answers until they had posted their own.
Then in March 2011 MDL-9376 broke this for me by preventing students seeing other people posts until the maxediting time had elapsed (i.e. a typical 30 minute delay before students could see other peoples posts)
This made the Q&A forum unusable in the classroom setting for me. I need them to see other students answers immediatly. If they were to cheat by posting a nonsense answer and then updating it I would probably see it as I am there in the classroom.
I then hacked the fix in the code so it didn't apply on my own installation but I was wondering if other people have had the same experience and if it is worth investigating creating a setting in the forum creation form that allowed this feature to be toggled. If so what should it be called, i.e. "Delay Display" or whatever.
