Because in general I would like indeed topic to be closed for editing… in this case it’s a category where people sell their old/used stuff. In the beginning people should be able to edit their posts as we have certain rules they should follow (photos, necessary information etc). After some time it’s safe to say the post is “finished” apart the price which can go down. People are allowed to “bump” their topic with the help of a button which appears 72 hours after last “bump” (whether bu button or some other person’s post in the topic).
So there it is … what I want to achieve. I have a button. I can bump editable posts but what if something is “in the market” for 2 years? 4 years?
