Ok, do you wonder why your signature hasnt shown up after you put it on? Well i will tell you here.
Below where your typing, look for a place called options. You should see something like this with checkboxes
Disable HTML in this post
Disable BBCode in this post
Disable Smilies in this post
Attach signature (signatures can be changed in profile) Notify me when a reply is posted
Make sure you have the blue line checked, or your signature won't show up below your post. PM me to make your signature AUTOMATICALLY be in your posts so ya aint gotta check it everytime.And say if you want to have a sign, but not have the smiley appeared. Check the box that says disable smilies in this post
Then you can type a face like this
=) :O
Hope it helped
