When does the light come on?

When does the light come on the left side of topic where the envelope shows up?

If its on, then it means there has been a new post since your last visit on that thread, and you haven't read it.

PS: I am moving it to support forum.

May I ask what's the difference between red envelope and the light sign?

[Nasif]

not too sure about details. The light probably is for threads that has high views or replies. This is just a wild guess.

hmmm. Interesting.
