Only mods can sticky your thread. Which means that you have to post something good or get really lucky by Hodapp's dice.
I know! They're so mean! You have to download the $30 'Stickies' app from the App Store, and then press 'Sticky Thread'.
*sigh* There should just be a Mass "I created this pointless thread and asked a glaringly obvious question for no reason so people can abuse me" Thread.
