With ludilog a user can create a game and invite other players to it.
After the "game owner" creates his/her first log file, he/she can upload it to the game page using the "add a file" button.
Then, each player will receive a notification on the site that something has changed in the game. Of course, the notifications will work for the messages that are posted on the game thread as well, so a player does not have to check the game page each time.
The game thread will be writable only by the players participating in the game.
