Two (and sometimes more) posts of the same person (and her/his socks) in a row. Sometimes it happens accidentally. In this case it's good to edit the second one and asking for a deletion. Double posts can be counted as spam, so it's wise to use the edit function, if one likes to add something to a post of his/her.
What Student said! If hit "edit" and just a blank page opens, then try to right click on edit and open it in a new window. That's works.
