I'm sorry, I don't quite know what you're asking here. Could you rephrase?
That was considered, and may still be considered in the future of this trial. But we do want all of the links available in all of the threads. If there's a lot of links and the game master wants to keep them tidy, they can be put in a spoiler box (please label the box, though). You can also create the list only once then copy and paste it, it doesn't really matter if a thread links back to itself...
Also, it wouldn't change the edge cases. Recruitment threads are often abandoned after a game is fully recruited, and if they're abandoned there's no need to link to them from the other threads. Threads in the Dice Roller forum still can't be edited. Plus, not all games have an OOC thread, and others might have multiple.
