I've recently tried posting some photos hosted at Dropbox. They worked at first, but then broke. I don't have an option to delete the posts. Why is that?
You can only delete the last post in a thread, i.e., before a subsequent post has occurred. I think you can also delete an entire thread you started if nobdy has replied.
You can 'rewind' a thread, by having each most-recent poster delete their own post, and so end up with no replies, and then you can delete the thread. I've seen it done a few times, and it's not so hard when there are only a few posts. So, for as long as my reply (this one) is the most recent, I can delete it. Then, Dan can delete his post, and then EBH. Finally, you're left with only the OP (Original Post) and you will see the 'Delete Thread' button appear in the bottom row of buttons.
