Edit the plugin's actual file, starting at Line 40, following the steps listed there.
Kinda... It Network Activates but doesn't show up under each site's list of intalled/available plugins. However, if they use the shortcode(s), the output will work.
How can I give back?
Please rate the plugin, Tweet about it (mentioning @TourKick would be appreciated), contribute code enhancements, etc. I do not want monetary compensation for this particular project, but thank you for the thought.
How do I add a "to the top" link?
Dynamic "To Top" Plugin is a good one that works site-wide, not just for this plugin. It might be a solution for you.
