This version fixed the duplicated tags problem that caused by plugin hook 'action_add_template_vars()' called several times and output is always appended to template variable '$related_tags' due to no initialization is done. And plugin option 'Tag(s) to be hidden' has been changed to use TextMulti of FormUI. You can grab the updated version from the original post.
你好，我發現此 Plugin 有個 bug ，你忘了在 SQL 中將 tag_slug 也 SELECT 出來，於是每個 tag 的連結都會是 http://blog.tinyau.net/tag/{$tag}
@bcse：謝謝指正，新版本已經修正這個問題。 ;)
