Oh yes!! The FE equivalent of a black hole - sucks all 'work' in but never lets any out! We have just toughened up our 'file check' system. We post a list on Monday, collect in on Tuesday and give back with a chat on Wednesday! IN FE??!!??!!?!! I too used to take away the file's I couldn't bear to look at - til I realised that I had robbed that student of a learning experience - now I patiently explain, again and again, how the alphabet can be useful, or even the Index of Chapters in a text book! Stunned, almost explains their expressions!!!
