Unapproved comments showing

Was hoping someone could help, I more or less see what the issue is but not sure how to fix it. Using WordPress for a project I’m trying to finish up since it was a simple way of setting up a DB, comments and easy for administrators to add pictures.

Having issues with wordpress showing comments that were posted from the same computer I suppose as feedback telling the user that they posted something. The problem is this computer has many users at a library sitting at it potentially posting things throughout the day so I’d rather not have any unapproved comments showup at all.

I don’t know what’s causing it to showup however, it’s not in the theme as far as I can tell. I’m not much of a php guy, I can figure out though what to delete from where if I know what I’m looking for however. If someone could offer some advice I’d greatly appreciate it.

Thanks,
Matt
