Long time reader, first time poster. I recently discovered Bill Gates' new blog http://thegatesnotes.com. Upon first visiting the blog site, new visitors are introduced to the site with an introductory note--a lightbox appears; the user/visitor can close the feature at their discretion. (Subsequent visits to the site do not yield the same result, though once you clear your cache or reset the lightbox note does appear...I am assuming a cookie is dropped on the visitor's drive with each visit.)
A partner is looking to add a feature not unlike the one described above to their wordpress blog site. I have searched tens, if not hundreds of plug-in pages, to no avail.
Can some one please point me in the right direction and/or tell me if there is currently a wp plug-in available to achieve the desire result?
Thank you for your time and energy when responding, in advance.
