Since the old site was the target for a hacker attack a couple of days ago, I've now upgraded the site to run on the latest version of Joomla!. The most important data (articles, users, links and download contents) have been migrated successfully.
I'm sorry for the inconvenience!
There are lots of new free plug-ins available now in the Downloads section.
You find the Windows versions of the plug-ins here.
And here are the Mac versions of the plug-ins.
