When you go to post a reply (From a web browser), there is an icon in the "post your reply" box to the top left that looks like a chess board. Click that icon. Then select "Game or set of moves", select the "Use a PGN file" option, paste the text of the PGN in the field, then simply remove your opponent's name from the PGN.
You can get the PGN file by clicking the "Get PGN" button on the game you played after accessing it from your game archive. Once you download the PGN, open it and paste the text, then wherever your opponent's name is, delete the name and replace in with "NN" or "?".
After pasting in the PGN and editing it, click "Continue", then click "Next step", "Next step", "Next step", "Insert" (Bottom left corner) and you're done.
Hope this helps!
I know this has been covered before. But darn if I can see it. I would like to post the game I just played. Would like to deleat my oppoinets name also. Don't want him to feel to bad about it. Any advice on the procedure , thanks.
