I find that noobs that come to the analysis forum mostly just want to know how to get a game into a thread. So I mostly just tell them to copy-select the moves, click the icon that looks like a chessboard at the left of the message bar on posts, select insert pgn, and paste the moves. That gets the game into a thread, and when your clicking through it there is a button to turn on stockfish analysis, which is all they really want when they come to the analysis forum, mostly. Its a very primitive method of manipulating pgns, but it meets their needs in the easiest way.
All of which is a long winded way of saying that you might want to make the point somewhere in your discussion that for some purposes it may be sufficient to just copy paste the moves.
