80% of the plugins I investigate are full of bugs, crash my websites, and self destruct as later versions are released and I update them.
I am happy to report that this plugin worked, did as it said it would, and may be a plugin I use in my 20+ WP websites.
I'll play with it for a month before actually adding to my other websites.
Congratulations. However your plugin Hitsteps Visitor Manager blows up when trying to click the settings link.
But this plugin is a gem - hope it stays that way....
