I was going to ask how to place a diagram in a thread.
Just until now I noticed an object called FEN. Clicking on it, a diagram appeared.
Which leaves me to ask that Chessforums should have a help tag.
Just in case someone can not figure out what to do, or how to do it.

It also appears that more than several readers or writers in Chessforums ask
for information on Openings, Middlegame, and Endgame.
Possibly there should be a download section.
