Nice Titles

Stuart Langridge Jan 5, 2007

General

Display the title of a link in an easy-to-read box. Quick response time and very easy to implement!

Just hover over the links below to see it work.

Ma quande lingues coalesce, li grammatica del resultant lingue es plu simplic e regulari quam ti del coalescent lingues. Li nov lingua franca va esser plu simplic e regulari quam li existent Europan lingues. It va esser tam simplic quam Occidental: in fact, it va esser Occidental. A un Angleso it va semblar un simplificat Angles, quam un skeptic Cambridge amico dit me que Occidental es.
