Just be careful and smart. Don't view or post to this site from work, company phone or any other device on the Follett network. Don't discuss this site at work or with other employees. Follett has demonstrated that if they know who is viewing/posting to this site, they will lay you off in the next round. GuaranDamnTeeIt.
Even if they obtained the IP address, it would take a court order to have your internet service provider provide them with who was using that IP (just look at all the Napster type lawsuits previously, they would not release the user until a court order them to do so). I don't think a court would approve that since this is just a discussion board.
