Hi Ray
The main URL would be www.rotary-site.org - this will work fine, as the resultant link from a Facebook user would display this URL.
However, onee of the 'sub-sites' within the site, for example index.php?SiteID=314&lang=it anyone 'liking' the page would miss out all the paramaters and be directed to the URL: above.
Similarly, with pages within the sites:
page.php?PgID=385&SiteID=252&lang=en 'likes' are redirected to rotary-site.org
Cheers
Chris
