I think you need to add "@" or "mention" features as soon as possible it will boost the interactions with the forum active members
and moderators could easily track who is active and who are those individual that are very active in helping others.

And lastly the "post counter" it will give an insight to those new and old members how active they are on the forum.

What about "Custom Forum Title", I love it! 


Maybe you could add the "signature" feature as well :)

Cheers! :)
