Can someone tell me how to edit for sale ad?

That has been one of my complaints about this forum for a long time. This site is a little different than most other sites, if you want to change anything you only have a short time to edit (two weeks I believe) and after that time period you just have to go to the bottom of your post and list your differences either price or parts and hope that others will travel down the page to see what you have changed, or the other option is just to create another post with your new prices and parts and garbage up the servers with a bunch of useless posts. Most other sites that I go on will allow you to edit your listing for as long as your listing is available until you delete your post, I believe even the B Body and the E Body sites you can edit much longer but not this site. So just mark your other post SOLD and create a new one with your new prices or parts, at least your new post will be seen.
