Fountain Pen Board (FPnuts.com) now has been set to the default skin, "Club", featuring warm tones and indeed something of a "vintage" flavor. The original plan was to pin a skin to the board, with occasional switches for special occasions.
If you find the board resetting to prior skin, just log out then log back in, which should solve the problem.
CLUB, STONE, SALIENT and BLUE STEEL are clean legible skins. ZEN DRAGONFLY and ARIUM are a bit... fluffier. The basic IPB blue/white skin also is available, offering a bland generic look, but more real estate for posts.
Note that some use more screen space to frame the board than do others.
Others will arrive during the year to come.
I am fond of Club and Stone.
Try 'em out.
