Ok, here is an example.
For your first link, you would type in your signature editor something like
Brooding Chicks Outdoors
Then copy the URL (highlight, right click>copy
Then highlight the text above (Brooding Chicks Outdoors)
Then click the chain link and paste your url into the link field (click in the field>right click>paste) Then click Insert
There's an easier way (if I understand what you want to do). Go to the first post of the thread, and click the "#1" on the upper right of the box. Select the BB Code Link Snippet and paste into your message. When you then Post your reply (or place in your signature, I would think), it has the link and the name of the thread without all the html.
Looks like this:
