I have posted Amazon goldbox deal today morning at 12:00AM and it was my first post prior to other poster RaGe. But after few mins, I couldn't find my post any more. I'm not sure why my post got deleted.
One more thing I jus wanted to mention, ReGe replied to my post saying its a pre-post, but it is NOT. . I posted the deal after it was published in RSS feed which is after 12:00AM PST. She/He posted the same deal, same content from same RSS feed, jus few secs after mine. How could mine become a pre-post and not RaGe's?

Mods-
Can any one please explain this?

Sure, let's examine what really happened. Attached, is the screenshot of the revision history of your post.

Now as you can clearly see, you were first... to post a deal about some wireless printer right at midnight. But wait, at 12:01 it magically changes to ... "Save on Rocky: The Undisputed collection"

At the same time, RaGe420 (http://slickdeals.net/forums/showpost.php?p=27824864&postcount=1) posts the correct deal at 12:00. While s/he posts the actual deal a few seconds after you, your deal was for some non-existing Wireless Printer, hence your post is a pre-post, and as such is deleted without any reservations.

It looks like you are also not reading your ModAlerts (http://slickdeals.net/forums/modalerts.php?), your Warnings (http://slickdeals.net/forums/Warn.php?do=ViewMyWarnings), and your Private Messages (http://slickdeals.net/forums/private.php), as all of this has been previously communicated to you.

I got it, thanks for the quick answer...I copied the yesterday's deal and went back and corrected. My bad!
