Bold - left text only

[Summer-Time-Fun]

Hi

I know when you view a thread, it turns from bold to standard font to indicate that you've already viewed the thread. But I noticed in some threads, although the title text is not bold, sometimes the first part of the thread title "is" bold. What is the difference between a thread title being all bold, to just having the first part of the title bold? I mean what does the later indicate?

Example:

Thank you

When you start a thread in the download section you can add a Prefix for Clip or Pic.
The one that are not in bold where done before there was Prefix added and are type.
