Can't really say I'm new, because I have been lurking on this thread for several years However, I thought I would chime in with a formal introduction and mention my blog Forgotten Runes were I have posted many of my old school maps ( and some new ones too). Here are some of the most popular:

Old School Dungeon the Maze
Ruins of Thetra Mage College Above Ground
Notebook Doodle Dungeon *got to come with a more catchy name*
