You're being a twit, to most on here and on the internet I should think, bumping refers to bumping, a needless act to get your post to the top of the message board. I provide price reductions, updates and notifications. If I sell another domain in this thread I will say so, I suggest you go talk to fellow admins and discuss what exactly bumping is and get back to me.
If you just want a noticeboard with no replies and no updates and no price reductions which will lead to a stale forum due to overzealous admins and no bartering or exchanges, then go for that option. Just make sure all know that's how it is. Freeze the thread if you want, I can start a new one five minutes after as per the rules.
You need to read up on what bumping is, yes I can update the first post but who is going to know it has been updated? only God and he aint buying.
