hook location not in plugin manager

[Lynne]

The members popup things on *what* page? They show up on several pages. You need to access a hook that is used when that particular popup is being rendered. For instance, if you were adding it to the posts on the showthread page, you would use the postbit_display_complete hook since that hook is accessed when the individual posts are being rendered. You need to do similar for wherever else you are wanting to add this.
