If you didn't check that option then only mprep (local moderator) and global moderators would be able to delete posts. If you want to be able to delete posts then check self-moderation option.
Okay I think I'm almost there at understanding, so I swear I checked the Self-Moderated posts before I created the thread, and maybe I didn't, but I should be able to delete anyone's posts on the thread if I did, correct? If I can't then I'm guessing I somehow didn't check that box. Thank You for the help by the way
It would look like this one https://bitcointalksearch.org/topic/wall-observer-btcusd-bitcoin-price-movement-tracking-discussion-178336 where there's a blurb about self-moderation...
maybe start afresh, check the damn box, and link to previous thread
