Smart Hashtags [#hashtagger]

Free Plugin for WordPress and ClassicPress

This free Plugin for WordPress and ClassicPress allows you the usage of #hashtags and @usernames in your posts

This plugin uses the Tag system of WordPress resp. ClassicPress to automatically convert a #hashtag into a Post Tag. Each #hashtag is added as a “normal” tag (without leading hash) to the post, so it is fully compatible with existing tags!

Furthermore this plugin enables you to use @usernames to automatically create links to a users profile page or website and $cashtags to automatically create links to show the current stock value.

You can use #hashtags, @usernames and $cashtags on Posts, on Pages and on Custom Post Types within Content, Title and Excerpt.  There are a lot of settings you can customize.
