Display the Tag Cloud or the Archive directly in posts and pages, and change their look in the options.
[POSTTAGS]in the post or page content.
[POSTARCHIVES](Notice Plural in both cases!)
(For the mad tweakers, you can also add the php code
<?php pta_posttags(); ?> or
<?php pta_postarchives(); ?> to your templates to show the cloud/archive. I guess it's basically the same as the default WordPress feature, just with easier options)
