I'm trying to write a post, and I know Greenpawn gets grumpy if there aren't a few diagrams to help along the way 😉

Starting position in a chess game:
rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR w KQkq - 0 1
Unless there is an en passant capture available, all you really need is the position, who is to move w or b and if castling is possible.
rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR w KQkq
w - kq means white is to move and white can't castle.
b - - means black is to move and neither side can castle.
The following articles give more info in case you need to allow an en passant capture.

once you have your fen typed out, then to post the diagram on RHP:
Enclose FEN in bracket [...] 7K/8/k1P5/7p/8/8/8/8 w - - [/FEN]
That is fen not FEN [/fen] -- no / before the beginning fen.
P.S. I thought I knew how to post it. But apparently it does not always work unless you get everything right according to RHP rules. The FEN has to be in lower case letters on RHP apparently. fen not FEN
