Display message at login, maybe just once?
I'd like to be able to display a message at login on our iMacs, perhaps just the once, or maybe each time - depends how easy it is to set up and maintain!
At present, I have a student share folder where students can dump files/documents etc for their peers to pick up, utilise, borrow, steal whatever.
At the end of every term I empty this folder as it invariably gathers a lot of rubbish.
I'd like to display a warning message to this effect, warning users that the folder is due to be emptied and that they should recover any work they desire to keep.
Displaying it just the once would be adequate, although a message displayed every time someone logs in would be quite a useful tool too!
This just isn't going to be straightforward is it?
ANY help, hints, tips or pointers very welcome!
Running iMac's with OS X 10.5.* and a shiny xserve :D
