Been using the Newark Irregulars website for news about up and coming wargame shows for years but only just noticed that they have completely revamped it (and the rest of their website). Its laid out much better now and is split into dropdown menus for different countries/continents, by month and then gives details of when where as well as if there is a website or not for further info.
Excellent stuff :)
