My laptop is quite glitchy or it has a bad connection or something, but when I post, sometimes I double post [glitch] the same thing. I go to delete, but I cannot. :|
If you want to delete a post you need to click edit post -> delete tab -> then a small dialogue box appears under the post where you must click a bubble that says delete post for it to take affect.
I had this problem the first few times I tried to delete a post as well. If you clicked the bubble then I don't know what to tell you.
