So there is no way to bump a thread? I mean, not everyone is looking on that very day a person lists. Would a bump every 5 days be acceptable as long as you're not having fake conversations?

It sucks that people would probably abuse this but i think not allowing any bump but price drops is a bit rough. For example, i've sold a lot of things on superfuture in the past week but on different days. If someone hasn't been on sufu/styleforum for 2 days, they're probably not going to go 3-6 pages deep in the buy&sell forum and might miss something. I just sold 2 things to past 2 days from a simple bump. I undersatand that too many people would abuse this though so i guess there is no easy way around it.
