They seem to be numbered in sequential order and we're up to approximately http://drownedinsound.com/community/boards/social/4478066 now.

Just link to a thread that is yet to be made by amending the number in the link to one that is higher than where we're at now - the link won't work yet, but one day, when that thread arrives, it will work. Then you'll be able to see if your prediction came true.

My prediction (not too far away so I can check it in a day or so): http://drownedinsound.com/community/boards/social/4478077
