I think they're quite pretty - but I don't know what they are for either, I'm afraid.

John at this stage I'm going to blame Van for tinkering (sorry Van), we have left a message for when he is next online.

Sarah

The blue stars only seem to appear in the posts of those with a link under there name. ie To the Safe and Sound or Apartments to let etc.
Although they don't show up on the peoples posts when you are typing a reply!!

It appears that the signature divider line has been changed from a solid black line to the more colourful blue stars.

I'm sure Van had good reasons for this.

As Sarah has stated in her previous post, Van has been made aware of this topic, and I'm sure he will share his reason for making this change with us in due course.
