TinyMCE Signature

• TinyMCE Signature is a plugin that lets you add a signature widget to each of your WordPress posts. It makes use of the popular TinyMCE text editor, allowing you to customize your signature with different font styles and graphics. TinyMCE Signature gives you the ability to display your signature on all posts and all pages, or only on certain posts and pages. All customization is handled through the WordPress dashboard. The TinyMCE Signature plugin requires WordPress 2.8 or higher and is compatible with versions up to and including WordPress 3.0.5.
  
  

WordPress Signature

• Like TinyMCE Signature, WordPress Signature lets you attach a custom-tailored widget containing your signature to your WordPress posts. By default, it locates your signature at the bottom of your posts. Location is not customizable, as of the time of publication. However, the content and layout of the signature itself is fully customizable via HTML. WordPress Signature requires WordPress 2.5.1 or later and is compatible with versions up to and including WordPress 3.1.4.
  
  

WP Post Signature

• On many WordPress-powered sites, you’ll have different administrators and users posting articles and blog entries. WP Post Signature lets you set custom signatures for each user. It also has support for WordPress vairables like bloginfo_name, post_title, bloginfo_url and post_link, all of which can be styled and added to your signatures. WP Post Signature requires WordPress 3.0 or higher and is compatible with versions up to and including WordPress 3.1.4.
  
  

WordPress Signaturer

• WordPress Signaturer is yet another plugin that lets you insert customized signatures into your WordPress posts and widgets. One neat feature it has that many other signature plugins don’t is automatic RSS feed transformation. Simply add a line of text between two hash tags in your signature and WordPress Signaturer automatically converts the text into a link to your blog’s RSS feed. WordPress Signaturer requires WordPress 2.8 or higher and is compatible with versions up to and including WordPress 2.8.4.
