you can delete your own posts for only a limited amount of time. go to your post that you want to delete and check to see if the edit button still appears down in the area where you will also see the words reply, hugs and thanks. if the edit button is gone then you can not delete your post by yourself.

to delete your post after the time limit look to the left of the post where it says your name and down under there location your profile information. at the bottom in that area are some little buttons. one usually a red triangle says report when toy put your curser on it. click report then fill in the space why you want to delete your post. then submit. then this report goes to all the moderators, the moderators that work that forum board where your post is will read the report and if possible do the deleting of the post.
