Thats better - damn academic being a pain in the neck and I'm wasting time trying to be 'nice' in my email replies. I would prefer to say
'The systems were changed because the message boards that are in blackboard are rubbish and everyone complained about them. The whole team agreed to use this system which is like the forum system we've used for several years - there are a few minor things that you can't now do but on the whole everyone bar you and one other person have been very positive (including the students). If you want me to reprogramme the system to do these couple of minor things then I'll add it to the list of thinks to programme/update. The current list has over a years worth of work at the current time.'
Sorry - just had to let off steam, I think a 'Doom in god mode and chainsaw' session will occur tonight.
