The layout of MCiOS is similar to York - plain unordered-list text in 'player: move' format; but several innovations that first appeared here have become common currency across the Morniverse; pre-coloured names, move preview, move permalinking, the ability to step from one game to the next, and so forth. There is also a [live chat server] with an embedded Flash-based client, a hitherto undocumented HTML-style <HIDE> tag, a bad advice server, and a few other minor enhancements. The code itself, Dan insists, is quite horrible, for reasons identical to those given by Yoz? with reference to Delphi.
Other names the site has been known by include 'Outer Space', 'Parslow.com', 'Dan's Server' and, infrequently, 'Eighth Dimension'. (For a brief time the server was named Mornington Crescent Across The Eighth Dimension, for no very compelling reason.)
