how do i activate signatures for users to display?

You know the signature part at the bottom of posts made by users, how do i activate that for my forum to display it pls? It has the option to put in signature details within the user profile section but it doesnt show when posts are made.

Thanx.

i have read the section in regards to signature and i have done all it said but still no signature showing on posts, hmm strange.

Check in your profile (via the navbar) and check if in preferences "Always attach signature" is marked on yes

P.S: Next time, use the edit button
