Yes I know this has been discussed before, but it's been a while, but the issue has just surfaced here. We are having a new head in January and in one of the recent meetings he's been attending he described the sharepoint system at his school. So he's keen to introduce it here.
I don't particularly care for sharepoint myself, but I'm willing to hear what you lot think about it.
Also another possibility is the Sims Document server, unless I'm misunderstood what it does.
I'm installing knowledgetree as we type.
Any other notable systems?
