WP-TwitterBadge is a simple plugin that allows you to display a Twitter "Follow" Badge on your site or blog.
It uses the Twitter "Follow" Badge that is provided by <a href="http://www.go2web20.net/twitterFollowBadge/" rel="nofollow ugc">go2web20.net</a>. This plugin takes the hassel out of having to manually edit the details and enter it into your theme each time you change themes.
I’m providing this plugin as it is since this Twitter Badge is actually written and maintained by <a href="http://www.go2web20.net/twitterFollowBadge/" rel="nofollow ugc">go2web20.net</a>. However, I will be fixing bugs that are found in the plugin and updating with updates from <a href="http://www.go2web20.net/twitterFollowBadge/" rel="nofollow ugc">go2web20.net</a>. That being said, your feedback is very important!
I do not claim ownership of any part(s) of the included "badge.js" Javascript file as it belongs to <a href="http://www.go2web20.net/twitterFollowBadge/" rel="nofollow ugc">go2web20.net</a>. This javascript file is provided via this plugin as is and with no modification.
