A user of my UBB informs me that there is no date or time of posting to the right of the word "posting", which appears after the postit icon. Do you have any idea as to what could be the problem, and how to solve it? I didn't think this was a configurable option. Thanks.

It's possible that something the user is doing is filtering Javascript. Have him check his profile/preferences area to make sure that he's set his time preferences.
