Thanks Mark, that's the easy bit. I'm wondering about how I pass the session.auth.lastlogin date to the UDF, given that each user on the site will have a different last login date.
Or can UDFs just access the session variables the same way the main page can? What the function has to do is figure out whether this article is new or updated FOR THIS USER since they were last here. I have the user's lastlogin date, and I have a date added (i.e. NEW date) and dateupdated (i.e. last changed) date, so using those three dates I can work it out, but I don't want to have to put all this in dozens of places on the site: [pseudocode] If session.auth.lastlogin is less than document.dateadded - show NEW.GIF IF session.auth.lastlogin is greater than document.dateadded and less than document.dateupdated - show UPDATED.GIF Else - show nothing.

Assumig you have a date for when the document was submitted, you can use a DateCompare (date1, date2) to decide which one you wish to display. Or is there something I'm missing here?
