This may seem counter-intuitive, but is there a way to run a UBB board full of topics that lets users post, and review their own posts, but does NOT let them see any other posts?

I have been charged with setting up a system whereby internal and external staff can submit ideas to a list of proposed projects and reports. A quick and dirty way to put in their $0.02 on what the company is planning that can be viewed and retrieved by moderators. The boss would like this input to be viewable by the moderator, but not by other posters. He feels this would help people be a little freer in providing input.

My company is currently running a public UBB-driven board using v5.4. Since the costs are so minimal to run two licenses on a single site, I would not be opposed to upgrading if that's what it takes.

Any input is appreciated.
