I've finished (well, I guess so at least) my newest WordPress plugin. You'll notice on links mouseovers the number of clicks they have received : that's what my plugin does, keep track of link clicks.
I'm pretty happy about the result. The plugin is extremely configurable, is a real plugin and not a hack (install, activate, forget it : it works without further work, no need to edit your index.php or change anything to your posting habits), and I have learnt a lot about PHP and WordPress engine. Hey, I mean, I've even understood what preg_replace_callback is :)
I'll let the plugin roll for a few days, for final testing before I release it. I know I still have one bug to fix but the rest seems running smooth. Please let me know if you notice anything suspect :)
