I know a forum (and I am sure many of us know it), where single freebie thread already works and ... it just works, nothing more to add. Very good idea of the one who created this thread is that it is no-comment thread. Only title + link (+optional posting author notes). Nothing more. This way thread stays clean and you can quickly check if there is anything new / anything interesting without having to skip everyone's comments on this or that offer. Another good idea was moving all those comments to separate thread. So ...
Single thread with links only + Single thread with comments only
this solution really works.
