delete posts

How do I delete posts without deleting the entire thread as the little button deletes entire thread.
all i want is to delete specific postings without erasing it and leaving blank post

On the post itself, there must be a delete button. Don't you see it? If not.
Display>pics management
Advanced mode.
Buttons tab
Delete this post :
