Hello

I was wondering if it is possible to highlight (for example make italic or bold) new replies to a given post.

That is a CSS issue.

The software decides wich image is shown in front of the posting subject (the thread-sign or the arrow) with a cookie wich stores your last visit. This is realised through four classes with self explaining names ('thread' and 'threadnew' for opening postings, 'reply' and 'replynew' for answers). Set a background-color for a.threadnew and/or a.replynew.

Attention: This solution is cookie based. A posting will be shown as new for a given time independent from the 'readed or not' status. If you want to mark unreaded postings you have to handle with a:link (unreaded) and a:visited (readed).

Tschö, Auge

[edit] for information: I don't know if it is a new feature or not, but as a registered user I have an additional class 'visited' in the link wich stores the subject.
