Contributors with no ‘Comments’ possible?

Hello. I’m using WP 2.1.3 with a customized theme.

I have read several posts with the same issue. I want to allow other people to post articles by electing them as contributors. But the biggest issue is that they will be able to see the e-mail addresses and IP addresses of those who posted comments under ‘Comments’ tab. Although I really want to allow other people to write articles, there is no way of me allowing them to see other people’s private information. Has anybody found a way around this issue to allow people to write articles?

Thank you,

T. Bluewater
