I've been seeing all of these posts with links to people's story. How do i create one of those and add it to my signature?

First, post your story in the forum that you would like it to appear in. Then, you can link it in your signature in the User CP section. That link is in the upper left hand corner of the page, on the purple bar. In your signature, you can use this code to make a name for the link, and add in the address. You can use URL Hyperlinking directions - and that is about half way down the page.

You can create a signature after you've been a member for about 30 days. We had to put a delay in there to prevent spamming.

Let me know if you need more help.
