Hello to the developer of this excellent plugin!
(I failed to contact you from your site, hope you will see this message.)
I made several bug fixes and updates to CYC, so it will work well with 2.9.x, woek with more kinds of themes (esp. those that float things around), work with bot rtl and ltr sites, and so on.
I also added a few features, mainly involving options to simplify the registration and profile.
I would love to send you these changes so you could integrate them to the next release of the plugin. You can email me (yonat att ootips dott org) or leave a message here to tell me where to send the updates.
Thanks for the great plugin!
