How to set reply alert?

I have to check each thread when i came back.
That's was very tired.

I want to have a reply alert so that i will know who has reply my message.

Merry christmas!!

I think that if you don't clear your cookie when you r out then when you are back, only the thread that you not viewed yet (or viewed but someone replied) will have the "new" symbol. Just think :lol

yes, and also you can see who replied that topic on the topic list: Last Post.
