perhaps it could be for paid threads only? one can hope!
my only issue with this is that nonladder has a much different market than ladder.
non ladder tends to be more revolving around pvp items and ladder is more revolving around pvm items.
I don't think it's very logical to flood non ladder with every reset, it's also easy to copy and paste into a new thread and paid topics don't cost too much to bold/red a fresh topic.
I also feel as though you are more likely to get interested buyers on fresh topics rather than a 2 month old topic with 30 bumps.
just my opinions glgl
