Hello everybody: (excuse me my english is very bad. I'm spanish)

I have saw that in this forum it use a check box that i'm interested very much.

The check box is <i><b>Check here to be notified by email whenever someone replies to your topic</i></b>

The administrator or webmaster can tell me how do it? is it a MOD for snitz forum?

Please, if anybody know how i can make that check box tell me.

Thanks a lot.<img src=../images/dmxzone/forum/icon_smile_approve.gif border=0 align=middle>
