Hi, I'm new to wikimedia and I have a few questions about modifying and designing skins: 1) Are the interfaces for the Skin/SkinTemplate class families documented anywhere? 2) Do the Skin interfaces actually provide any facilities for abstracting page design? Looking at MonoBook.php, all of the work seems to be done in the execute method, and it looks like pretty standard html/php/css - there doesn't seem to be a particular wikimedia code idiom. 3) Is there perhaps an existing skin with a more transparent design I might use for study and modification? Thank you, Jay
