Now available on JGF. E.g. (using Kev as a guinea-pig):

…also demonstrating the ability for multiple people to post to the same diary.
How it works is that each game has its own diary (or not), and all the people who are marked as authors of the game can post their own entries into the diary. It records the name of each poster just to keep things clear.
I just put this together very quickly tonight, so right now you have to ask me to create the diary for you (just takes a couple of clicks) but I’ll try and fix that ASAP so you don’t even need that.
I’ll also setup a news feed on it so that new diaries + updates get sent to the news section automatically (like they do with new games)
