Activity streams cut long texts and show an excerpt, and some items have no direct link to that exact content. This plugin solves the problem by placing a link below the excerpt which will either expand the text with AJAX (if a wire comment) or open a new window with the direct link (e.g. blog posts and comments).
If you have any problems with the plugins, please visit our <a href="http://netweblogic.com/forums/" rel="nofollow ugc">support forums</a> for further information and provide some feedback first, we may be able to help. It’s considered rude to just give low ratings and no reason for doing so.
If you find this plugin useful and would like to say thanks, a link, digg, or some other form of recognition to the plugin page on our blog would be appreciated.
