Hi Thom,

If the URLs are always the same and must appear on every post, you could simply add the code to the single.php file in your template directory.

If they are different everytime, it sounds like you mighy need a simple plugin that fires whenever a post gets displayed, and then pulls the fields from a database or from a custom field.

We might need a bit more info, before saying which way is the best to go..

Hope this helps so far

there is a really great and easy to implement plugin just go [dagondesign].com/files/dd-add-sig.txt save it as .php file to your plugin directory and you will find DDAddSig under settings and viola html your links in and they will be visible under every post, when you activate DDAddSig.

I am with Bruce, are you looking to do the same links every time or are you looking to do some kind of related posts?

For the same links, you can easily add those to the loop. For the related posts plugin, there are MANY available.
