Is it possible to transfer/reassign ownership of a game link...

...from one player to another player? In my particular case this would be from an accidentally anonymous player (my friend) to a registered player (me).

My friend and I happened to be in the same house. We thought we'd start a game, and play a few moves so that the game would persist. It seems that he forgot to log in at the time. I infer this from the current 'anonymous' tag for white. His laptop has probably been turned off in the last 3 days. The answer to http://en.lichess.org/wiki/Common-Questions#011 seems to imply that he won't have the original private link.

It doesn't seem possible to resume the game. I imagine providing the url to him would let him see the game as a spectator.

Is it possible to transfer the ownership of the game link to his account? At the moment (I think) the game can't be played.

(github.com/ornicar/lichess/blame/master/TODO#L7)
"start game with any custom position - position builder" seems to be 7th on the TODO list . I'm guessing that this might be the best option, especially as transferring/reassigning the link would basically help us workaround our carelessness. However, I thought I'd ask whether there's some existing Lichess solution or workaround.

As an aside, I was wondering why the comment "Upgrade vendors" is on the same TODO list line as "* start game with any custom position - position builder".

oops... I meant " from an accidentally anonymous player (my friend) to a registered player (also my friend, when he logs in)".

It seems there's a reason why I'm talking to myself :-)

I just noticed the FEN string functionality - nice :-)

Does this mean that the position builder in the TODO list is for some interface other than FEN?

I just searched for 'FEN' and found http://en.lichess.org/forum/general-chess-discussion/whats-fen#1, where Thibault mentions PGN paste as well.

Out of curiosity, would the programming side of things map the output of any new position builder to FEN?

the real todo list is there: github.com/ornicar/lila/blob/master/todo you've been looking to the old lichess repository.

There is no feature to transfer ownership.
But indeed the FEN based games can save you. Click the FEN string of your current game, it's just under the board, looking like this: "1r6/3n1pkp/3Nr1p1/2pp3n/8/P4P2/BP3P1P/1R3RK1 w - - 4 25".
It will propose you to continue from this position with a friend. The rest should be straightforward.

Hi Thibault. It worked fine :-)

I clicked on the FEN string, and then copied & emailed the url. I logged out. My friend tried the link; made a move. I logged back in - the game was alive again.

Thanks for the link to the current todo list.
