Hi Miro,
I'm trying to set up something similar: if you read my thread dated 5th October ("IT-related question...") you'll see that MsCrow gave a number of options. Ms Crow, if you're reading this, I think I would like to go with the Wiki option, if you could advise me what to do next? I did look at the Ovidentia site but it was mainly in French which I can't read.
