all you need to do is copy the little code underneath where MrT put your Sig,
then click the profile icon at the top of the page..
At the left side there should be a list... click where it says
Forum profile information then down the bottom of that page there should be a blank field next to where it says signature..
paste the code into there and click
change profileyou should then be able to see it under every post you've made.
hope that helps
