You can add signature only after 20 posts. After you done 20 posts only then the Add Signature will be visible in your profile. Then you can add as you need.
Just go to user control panel and you see the option edit signature. but for making the signature you have 15 posts.and with use of signature you can get the traffic and quality backlink.
By go to user control panel/user CP and you see the option edit signature click on it and enter your keyword. but for making the signature first you have add 15/20 posts depending on site.
It is very simple, you have to go in user control panel and you can see the option of edit signature or change signature or you can check the FAQ for that.
I agree with wilphred. You have to go to the FAQs and Forum Rules to understand adding signature links better because if you just go to User CP directly without reading FAQ first, you might just get confused. You can only see the 'Edit Signature' option when you have reached their required number of posts. Here's the link so you wouldn't have to search it your self: http://www.affiliateseeking.com/forums/rules.php
