I agree 100% with everyone - I just went in to tweak the settings so that you can only edit your own exchange posts for a limited time. I think that any changes should be made in additional posts as opposed to continuously editing the first post.
This does also mean though that if you are selling 10 items in a thread you cannot keep editing the first post to tell people they are sold. There are pro's and cons so we'll see how it plays out.
so this also made it to where we cant change the title anymore either correct?
