London Grid for Learning has announced that it's site will be changing. On the 28th June, they will move to http://www.lgfl.info and a preview of the new site is available at http://portal2.lgfl.org.uk/
The old site will remain up for now and be accessible, but no longer updated.
The former LGfL Portal of choice, Digitalbrain, will be closing it's doors at the end of July. Anyone still using the service will need to back-up their Digitalbrain content by the 31st July as anything could happen to it after that time. Namely websites ending up in the virtual limbo of Internet Time Machine sites and Google Cache but I wouldn't rely on those as a hosting solution.
