I'm working on setting up a Sourceforge account. It's a bit of a jungle getting all the bits and pieces together on that page.
The archive webpage is up there now atleast, and I'll start releasing new versions of Mediocre there eventually.
The Mediocre source code will be available through the CVS repository, and I'll see what else fun might be available.
New address to the archives is http://mediocrechess.sourceforge.net/.
