Hi everybody.

I was recently given the admin role on some little forum using your engine.
The engine is really great and all the users love it, however they have some suggestions. Maybe I could report some of them as suggestions for the development.

• Read/Unread posts
  What if the read/unread status was (maybe optionally) determined on a timestamp? The timestamp might be stored either in a cookie, or on the server, bound to a user and maybe to a category. All posts (maybe in a category) newer than the stored timestamp, would be considered unread.
  The forum would contain a 'Mark all as read' button, that would update the timestamp (maybe in a category) and refresh the view.
  What do you think?
  
• Ajax preview bubbles
  Possibility to show the bubbles on hover over the post title.
  
• Post title enhancements
  Smilies, images and links in titles?

All the suggested features were based on the needs of the users. If they can be achieved without changing the engine, then sorry for bothering you in this post. Anyway, I hope some of them might be helpful.
Especially the displaying of read/unread posts based on a timestamp seems to me a valuable option.
