The idea is that everyone who wanna offer for an item has to write it in the topic. Then no scammers can pm with offers etc. And if a known scammer writes in the topic, everyone can see it and warn the topicmaker. Also makes it easier for everyone to know current price of the item in the topic.
Dunno if this has been written before.
Or is there alredy a rule like this?
If not, is it a good/bad idea?
Please no flames Just trying to help
