when something is posted in the wrong place, we move it as a courtesy. we only delete things that violate board policy.
if you "lose" something you posted, the fastest way to find it is to click on your own user name. that will take you to your profile, which includes a link to a complete list of everything you've posted.
if you haven't already, now would be a good time to review the policies and instructions that apply to each section. you'll find them in bold-face titles at the top of each section. you'll be surprised how much you can learn about how to work the board. :-)
