Use the following steps to delete a scuba blog:
Login to your account. Click the “My Account” link in the top right, then select the “My Contributions” tab. Next, choose the scuba blog that you wish to delete from the list.
If you have too many items in your list, you may limit the items displayed to only reflect scuba blogs by selecting “Scuba Blog” from the contribution type dropdown in the search box and selecting “Apply”.
Once you're on the details page for a scuba blog, select the “Edit” link, then select the “Delete” button, and finally confirm the delete request.
